A

Welcome back everyone to the zamarons on net community stand up. This is this, is gonna, be a good one today, I'm so excited. Look at these beautiful people that we have on this should be, hopefully, one of the biggest and best done net community stand-ups yeah. Well, if you don't know what a.net community stand-up is- and it's your first one because he saw Miguel tweeting about it.

A

Well welcome, there's a few things that we like to do these happen twice a week for asp.net Visual, Studio, xamarin, Windows desktop and languages, and runtime on Tuesdays and Thursdays, and the first Thursday of every month, even though it's not Thursday it's Wednesday, because tomorrow is the 4th of July here in the States.

A

We talk about all the awesome things that people in the community have been doing have been, building have been sharing, and we also like to give you an insight into what is happening here at Microsoft and on the xamarin team, and today we have the awesome iOS team, led by Miguel up top over there and Maddie's here to go through so I'm James. If you don't know, I am I'm a program manager and we'll go around and we'll introduce ourselves before we go into the community link. So, let's start with Maddy awesome.

B

I'm Maddy Legere I'm, a p.m. and I work on tooling for xamarin forms.

A

Know I head over to let's say I'll, say it correct manuel de la pena. Yes,.

C

Perfect translation so well I'm subbing in here and I work on the I esteem. So that means doing bindings I'm, making sure thanks work on iOS.

A

D

Ok same way: malloc Soto I work at the summary in iOS them and make the product better and.

A

Miguel, who are you I,.

E

Think these guys are selling themselves short. These are the folks that make sure that every single capability that Apple brings to their platforms is surfaced in a dotnet friendly way that we have Seashore bindings, they're, fantastic, that they're tested. These are the magician in charge, and you know so that's what these folks are- and you know be. I I've been working in summer for a long time and that's why I'm here yeah.

A

That's why I wanted to have the team on you know we got to have we had last month or the month before we had John dick on to talk about the Android X work that was going on behind the scenes and like the the awesomeness, that's going into the migration and into the into the packages there. So it's great to have this venue to see all the amazing people that are get to work on the on the product that all of our developers get to use.

A

So we're gonna go first through the Community Links Maddie's gonna go through those and be like 10-15 minutes all the awesome things happen in the community and then we'll come back to the iOS team, we'll go through it and also feel free to ask questions in the chat room as well go for it. There go ahead, Maddie! Take it away! Awesome.

B

And I'll keep my eye on the chat but feel free to stop me if I miss anything so first of all feel free to follow along we're using the URL Escom. Slash xamarin stand up, July 19, so you can follow along with all the links for about to go through, like the community and some other things.

B

At the end, the xamarin forms for one release notes so jumping right in first of all happy July, it is xamarin UI July, which is basically back in December February February, because Valentine's Day Louise had to come up with an idea of doing examine month. So someone posted a blog post every single day for xamarin month and Steven. Thomason has decided that we should do it again in July.

B

You know it's been a couple months and do it for a UI focus, so folks have signed up for slots for every day this month, it's already full, which is awesome, and these folks are great members of our community and are gonna start posting about. You know UI things whatever. It is whether it's shell and visual or tools, or just some nifty thing that they've done for every day this month, so a lot of great content will be coming out and hopefully we'll be able to show a lot of them next month.

B

So there's already, which is great, the first one by Lewis himself and he is doing designed tools for zevran forms. So the first time I read this I was like I'll talk about a couple of the Harvey load things. Maybe it is crazy. First of all, there's a bunch of nougat packages about just good things.

B

You can add like cards and animations and FF image loading which I know is really popular, and then we talk about custom controls, including some of our awesome vendors, like sync, fusion and telluric and gryal, who have been working on this forever and have some amazing controls, an aurora and then previews and hot reloads. You can use and then other extensions that help you out when you're building new eyes for xamarin forms. So this is a really great article. I I mean I, do xamarin forums, tools and I've.

B

Read this through for like four times now, just trying to figure out what I can steal from from these great ideas and great products that are out there. Yeah.

E

I saw this article as well. I was it's a really good article, in fact, I think even retweeted. It I tend not to retreat too much to spam, but this was. This is really a good piece really the piece it has all kinds of very interesting pointers, and you know once you are ready to graduate from the simple samples. This is a great way of spicing up your app yeah.

A

And in some ways, there's so much happening in the community, we'll talk about like blog post, where it's like here's one, here's one and then it's like you know it's good to see them all come together. Yeah.

B

Absolutely and there's so much and it's cool because every month, there's more stuff to add to this kind of stuff. So yeah.

E

Those in particular the one that you have on the screen, those are really nice. The shirt transition, one because it's kind of a pain to get it right and and I remember when this was in its infancy and it was like well here's an idea- and maybe we can make this work. So it's very nice to see this mature and the same thing for some animation yeah. These are. It is really good. It's a good list of resources, yeah.

B

It's awesome cool all right. The next one is by Steven, who is you know, heading up the July July UI is a marine UI July, oh my gosh, and this one is about using base pages for zamel, which, if you follow me on Twitter, was a something I asked about a few months ago on how many people will do. This turns out more than I thought, and the idea is that you put all of your navigation and such in a base page, which is kind of what we do for you in shell.

B

But if you don't want to use shell or you have an existing app and you're trying to abstract out things that you know already exist, he basically puts all this stuff into a base page and then uses it on all the other content, views and pages and anything else that he has in his app, and he makes this really beautiful sample banking app down at the bottom here.

B

So all the codes on github, as always, and if you're looking at you, know ways to reuse a lot of your code, especially like your tab bars and your title bars. This is a really good way to do it, so I definitely check this one out all right next ooh. This is an app that people actually just shipped with xamarin, so it is Daniel causer and the Toronto meetup like meet up com.

B

Basically, they decided that they wanted a better way to get feedback from attendees for their meetups, so it hooks into the meetup API and as an organizer, you can connect with your you know the attendees and publish all your surveys and see all that data that you get back and as a user, you can download the app and actually rate the meetups that you've gone to. It's also cool because there's a way to get prizes, which is a lot of fun.

B

So it's this Amran app and you can download it now and use it with your meetup. So if you're, a meetup organizer in your area, cool, so Daniel also had a really good blog. A couple of weeks ago, a week ago, ended June and he was talking about just some tips and tricks that he's picked up using sequel Lite in xamarin forms.

B

So there's a bunch, so he talks a lot about performance, which I know is a big thing with databases, some other tricks like pragma queries, which I had no idea what they were until I read this and I was like oh that's, cool and finally, just tools that he uses that help him make his life easier, while he's developing xamarin forms and sequel Lite together. So he's been very busy this month. If you can tell and I know, just like he regularly posts on this blog with more stuff, yeah awesome.

B

What is next? Oh, my goodness, this one is really cool, so this is by Marco Marco folio net and he has an app or I guess, like a plug-in. Now that scans, your xamarin apps for security vulnerabilities, which is I, know something. People are very concerned about, but there's not always an easy way to find out the best things to do so.

B

He has this whole list of issues that he looks for in your app and your code and it spits it out to you and tells you where it is and how you can fix it. So if you have been worrying about security or if you're kind of moving your app from just an idea to maturity, this is a really good tool to download and it's on github. So you can go and take a look at all the source code, which is great.

B

What is next, oh, yes, Ren DS Google map styling, so Rendy has actually been doing a lot with Mac's lately, and this came out right after the last stand-up that we did where he had done like dropping a marker and then shown me how to do navigation and now he's talking about styling. So if you don't like the way that default, Google Maps looks or it doesn't really fit the vibe of your app, they have ways to style it in Google Maps, but he actually talks you through how to do that in xamarin forms.

B

There's also this tool called snazz map, which has pretty predefined maps that you can use, which, if you're not creative, like I'm, not creative, you can just use that, so that is a really nifty and also very short blog. So the code is really simple: you can get started doing it up and running if you're using maps, especially Google, Maps, right away, all right lazy view.

B

So this is sharp NATO calm if you're not familiar, that's John Murray, and basically this is when you have a huge page like a carousel view or a really long list view or something it takes a long time to load your page and sometimes folks, you know think the app is crashed when they navigate if it takes like seconds to load up.

B

So what he does here is build what he calls the lazy view and it's just a Content view that handles loading up a set, a second view, and it's got an activity indicator so that that'll, you know, show people that it's loading, but there's not a lot of code, and it really can make your user experience a lot better. So folks, don't think that your app is crashed and then quit it and reopen it or go back and navigate forward a couple times. A.

E

Little bit I mean it's obvious that I need to start attending this. Is they stand ups? More often, this looks pretty sweet. Can you go to the sam'l?

E

B

The view switcher so.

E

B

Is the EZ views in there and where.

E

Can you get the delays of you just I see what's going on here wow? This is cool yeah come more often the.

A

Things that the people build in our community are absolutely astonishing, so, like yeah doing stuff like this and being like, oh you know like here's. Here's how you can you know, don't load it all. Don't if you have a hundred tabs, don't load all hundred tabs into memory all at once, write lazily load them up. So it's kind of kind of cool to see that yeah.

E

B

E

Is fantastic yeah.

B

Also, the best part about his blog is that you can do all these different emoji reacts on the articles, so the best part- okay, what's next I, know we're flying today, but we have a lot of really great things to get to with iOS some. Oh, this is James's, so I'll. Let James talk about this one, but I.

B

Remember: James came up to me at those Aaron booth that build it was like you can do the coolest thing in the entire world, with asp.net dependency, injection, zamarons and I was like what so James I'm glad you finally wrote a blog about it. Cuz I know you've been talking about it for a while I, don't know. If you want to share your thoughts on this one yeah.

A

I mean this is people. If people follow me, they know I, don't like dependency injection and I OC. All that much. However Glenn Condren from the asp.net team has sort of convinced me that that maybe I should go all-in on things and the asp.net team.

A

They have this whole hosting model of sort of structuring their application to reconfiguration files and adding dependencies and they've broken it out of asp.net into this Microsoft Chin's, a library, that's just a nougat package, so this can work on anywhere and you can have a consistent sort of host builder of your application.

A

So, as you browse through the application, what's nice is that all of these existing extensions will work with your app so things like app configuration, logging, HTTP, client factory and then there's other things built on top of that, like poly, for instance, which does automatic HTTP retries. So if you keep scrolling on there, let's see keep scrolling I think eventually, I have like here's. The startup code keep going, keep going yeah, basically this or that chunk right there. So this cell will say: like here's.

A

My host builder I'm gonna read my configuration from the command line: I'm gonna configure all my dependencies, I'm gonna, add logging to it and then through magic of dependency, injection and constructor injection. All of that will be read into your application and then you can start using those services like HTTP, client factory, and things like that. This is this blog took me. Maybe ten hours to write I think there's a video that we did from build so like here you can add HTTP client, you can start using HTTP client and then you get these logs.

A

It's a little hard to see in that in that little screenshot, but there you go so automatically. You'll can start to use HTTP client factory, which does automatic logging of how long your HTTP requests are we're taking everything like that all for free. So you can take advantage of everything that they've been doing in asp.net in your xamarin app.

A

So it's a it's a long read if you got a long weekend coming up, have fun with that one now you do need the latest previews, because we made some optimizations in the mono runtime to support this, which is good, so it was really really fun to work on it. Like I said it's a long post, but I even go through how I like dependency inject, my entire application, so I just say like a new app and everything is injected like the page is injected.

A

The app is injected like services are injected, is bananas, so it's super fun so give that give that a read yep.

B

And the build sessions at the bottom of the be blog, so you can watch James and Glen talk about it, IRL, which is awesome. So, okay, what's that Oh, so Charlaine Zam girl, if you know her from her website, did a guest post on the Microsoft xamarin blog, which is awesome and talked about device resolutions. So I actually always struggle with this. When I heard of build apps and I get really lazy and I just do on idiom, and you know that tablets have different resolutions and screens have different resolutions.

B

So what Charlaine does was take you through like how to find a bunch of device, sizes and I know. James and I had a tweet about this a while ago, looking for device sizes and then getting resource files based on the device size, so really dynamically scaling your UI, not just phone and tablet, but for all different sizes and then applying it to zamel. So you can see it just how much better this looks like the boxes are just slightly more spaced out and button like the word.

B

Login isn't like the middle 10th, it's like the middle fifth and it just looks way nicer. So, additionally, like you know on a small Android like this, is the Nexus it's all in one screen, which is way better. So this is on the dev blogs and it's a really quick read to it and Charlaine is really good with the sample code being interspersed. So it's pretty easy to follow along with cool next, oh alright.

B

So for all of you who watched, dub, dub, WWDC, I'm sure you sauce with UI and ryan davis, has been a big proponent, on twitter, on c-sharp for markup and continuous for hot reloading and a whole bunch of different stuff, and he actually joined on David or now's Twitter stream and David's on vacation.

B

So you can forgive him for not being here today, but he build out the login page for zappy, which is the xamarin forms demo app that David's been working on for a while with him, live on Twitch and he's using continuous, which is Frank, Krueger's and Vincent. Each is C sharp for markup and he kind of talks you through in this blog.

B

How easy it is to just get started building you know, UI fully of c-sharp, really short, not a lot of lines of code and if you're one of those declarative code based people, it is a really good tool to use if you're, not a zamel within so definitely check this one out, I notice. There are a lot of opinions on this if you've ever seen, it brought up on Twitter so feel free to fight in the chat um the next one.

B

So this one is Mart's and he had talked about like your own home media server and how you can connect that with xamarin forms and an app. So if you're, one of those people that, like likes all your stuff to be yours and you're, not a Spotify fan like I am. um This is a really good way to find all your media files at home and it's a zaman forms up so yeah.

A

It's a cool one, because Mart's worked. We talked about a few weeks ago. If you play that video, that's using VLC live from VLC, so they have official done net bindings and xamarin support throughout, which is really awesome. So this is cool because it has all the you know: SMB support through your local network, to browse everything that's going on, so it's like browsing files from like a network share, and then you know playing back video natively on the platform, which is like really awesome, like with very minimal code, so pretty pretty cool yeah.

B

And I think we had brought this up in last month's URL kind of dump blog dump how they had come out with that. So if you do, the URL list for June 19 um you'll find the link that original article sweet.

A

B

So next is Gerald and I talked about this a little bit last time, but I want to keep bringing up because I love this first of all, Gerald joined the xamarin forms team, which is awesome. Second of all, him and Steven have been working on snippets dev, which is a website literally just for UI that snippets, so beautiful-beautiful xamarin you eyes, and you share the code and you can go in and get ideas on it.

B

This blog post is a little bit about their thought process behind it and how they're partnering, with Planet xamarin, to get the community really involved and how you can just push things up on github and it'll be merged on snippets, so super easy to get started. If you have a UI that you know you, you have been sitting on and you want to share it with other people. That's the way to do it. Okay, the final blog! Well, I!

B

Guess we have two more blogs that this is the final blog blog is about performing improving performance with xamarin forms by Leo Mars, and she has some small things that are really good tweaks to just make your app faster and then some bigger things to so. You know, one of the things is just like using the right dimensions and your pictures and using the right layouts. So, instead of nesting stack away, oh it's over and over.

B

You know how you can change some simple sac, layouts to grids, and then there are things like enabling the compiler, which is one line, but if you didn't know it existed, you would have no idea that this is a really good way to UM you know the you know make your zamel compilation and your views load faster, also image cells, which I always forget to do so. It's it's a good short blog post and it's some things that you can go and kind of poke through your app and see what you haven't been doing.

B

That might actually give you a little bit more performance here and there. So the next two blogs are about the xamarin developer summit, which is next week it's an 8 days which is so exciting. It's in Houston on next Thursday and Friday. It's been organized by a whole bunch of great community members and it was started because David Orr now told Dan Siegel on Twitter. He should do it, so he did, and Daniel Koz were again had written a blog on five reasons. You have to be there.

B

I think they're great I mean the first one being community driven I, think that's awesome and the other one other blog here is Dylan and he's just talking about how great it is as well so I know, James and I will be there and David will be there. He'll be back from vacation a whole bunch of your xamarin folks that you're familiar with will be there and all like. Also our great community members. So a whole bunch of people and I love. This picture of food in Houston I'm very excited.

B

So it's there's still some tickets left it's not too late and I think there's still availability at the hotel. So if you really want to go like now's the time booked your ticket, it's gonna be great. We have some great announcements on the keynote on the first day, so finally, release notes for xamarin forms for one, so it's out, you can get it on nougat I think it came out Monday and we have a whole bunch new. In this release.

B

We have some WPF stuff, some mac, OS stuff and a bunch of things in preview, including collectionview, which we've added a lot of work to so definitely need to check it out. As usual, we have our fantastic. Thank you, which is the new thing. We've been doing with release notes. Look at this list of contributors. It's amazing! These are all the people who have contributed to for one so huge release, I, definitely pull it down, and you can always see the API changes really easily. With the release. Notes am.

A

I on that list, I want to know my check box.

A

B

A

In there, I'm already using it in one of my apps.

B

A

B

All day, I guess.

A

B

A

I work at Microsoft side: oh I'm, not really community contributor, but I like to think.

E

A

That's what's going on.

E

Yeah, which is good I,.

A

Do want to say that it was my wasn't my most my largest out there and Robert asks. When will it go out? Go out, it's already out Robert, it's out. It's available out there and yes check box is available and that's the most important thing that has happened in my life.

E

A

Least the last five years so and.

E

Yeah I mean you know why we resisted checkbox, initially right.

A

Oh I know: well it's hard, it's a hard one, because the iOS implementation there is nothing on iOS. Well,.

E

It's just that you know part of the idea is that it forces the idea was to force people into thinking of alternative user interface elements writer. hmm What would you do if you didn't have that and anyways? That's about the reason, as a reason why we didn't do it to kind of promote people building more native, looking apps, but.

A

Now you got a checkbox and that's all it's all I ever wanted Miguel. It happened. Yeah, I, guess.

E

I guess life away like the.

A

Circle of checkboxes.

E

Find a way they.

A

Do well thank you, Mattie, so much I know you got to probably head out and you have a hard stop here, but thank you so much Matt, thanks to all the awesome community members to for, for all the awesome, can contributions so yeah. So, let's just hop into it. So iOS 13 preview, its out is that correct. We have a preview available.

F

Yes, we do have a preview for.

C

At scopetta, too, of course, a poll decide to drop an Xcode better three, so you can try out you're gonna find a small issue where we added a framework done later, which we moved in better three. So if you bump your Xcode about two three make sure you're using the linker and that will allow you to make a eleven applications without having a an empty ever telling you the frameworks not found in Xcode eleven, but the three but yeah you're, it's out, you can try out.

C

You can right start writing applications start using some of the new frameworks that we got it and everything you will find to be able to deploy to an X, K and I of the team device as well on tested with your simulator. So.

A

I think a lot of people may not understand how like how how it works right, like how does Apple does a drop of Xcode and then magically people install preview bits and things work, but I think that a lot of people don't understand like the magic that your team and the team put does to make this all happen. So I figured like. Maybe you could take us through the process either man, well you or or Alex.

A

If you want to take through the process of like how does this magic actually come together, cuz I know it's not easy necessarily, but we were talking before you said it's not as hard to get in and look at it and start contributing to so. Do you want to kind of walk us through a little bit of like how this.

C

A

Comes together and I'll monitor.

C

In the chat and.

A

I'll monitor the chat rooms too. If people have questions feel free or from anyone else wants to chime in go for it, so go for it. So.

C

We were talking previously and we think that we don't have done many contributors, because the word buying some scary, which is understandable but he's not as scary as you may think. Alright, so what we usually do in the team, we usually call these life in the ESCO 11th season. For some reason in my brain I make the analogy with hunting season I just picture themselves with guns after frameworks, so this is actually 11.

C

We are in X, let's see some and we do all our work on github, so I'm going to share my screen, so you can see our project and ideally I'm, going to tell you well, where is everything, and how do we work with things right? So most of the work happens in that specific branch, so seems we're working with that 11 would be the ask 11 branch, which we branch from our latest stable and we start adding they're all the new frameworks right.

C

So what the very first thing that the team does is look at the differences between the different X codes and the different methods, so the fastest and easiest way to see where we're at is through the wiki of the petraju Grandia table. So if you go to the two wiki you'll see that we have a bindings.

C

Heading here and you can go and check out where the binding state is a specific exclude version. So that way we deal with this is we generate piece of the headers of each of the frameworks, so, for example, if you want to find something, that's all your toolbox, you can click on it and you'll see. All of this don't get scared we'll get like alex is going to explain that. What how do we do with this?

C

So what we do is we use this table, which is also generate that and here at the bottom you'll see expense how to tell them.

C

What we are doing is we are providing the dates of eight each better so that we can see what changed and then you'll see here, Armando what we usually developers name next to the framework is working on, so that we don't step on each other. It would be very annoying if you know you work in a framework and then someone else is we're gonna same framework and you got to pr's yeah.

A

And what I, what I'm seniors? It's like when you say X, like people just think iOS 13 like this- is not just I Oh s 13 for the phone, but this is everything and also I, assume I've gotten a billion questions about iPad OS, like that's just iOS right, that's like everyone is like, is Amer and supporting iPad OS I'm like I'm, pretty sure it's just a marketing name, but yeah.

E

Let me take a step back just hear what essentially, what we do when, when xcode season as manual calls that when we do call it that when the xcode season starts, is we looked at?

E

What change in the api is because we want to make sure that ., --an and developers have access to everything right so like when m was saying the the changes in the platform are done in all of these frameworks, and that's what you see on the left side, column, which framework so which changes did, for example, I'm looking at, let's take a look at the rope close to the bottom. Oh no, that says nothing authentication, services right. This is the new stuff that Apple introduced.

B

E

Right so that row, and and essentially we track all the changes that Apple does on the better one, the better and the better theory right and we and we have the practice across the board- that's why that there are four columns, one for each of the platforms that Xcode supports and what you see you know you can compare that. There's two sets of cells right in authentication services. There's the PR!

E

That's a link to an actual poll request where somebody in the team already did the work and what we try to do is we want to have multiple eyes, take a look at the the patch right. So so we don't we no longer just commit directly. Instead, we ask folks in that team to review it to make sure that we that we follow our own conventions that we you know, we use the proper naming and things like that.

E

And it used to be that that we could just there was one or two people that did the binding, but now there are more people working on on this. We kind of have to look after each other. So that's what we do it now through poor requests and- and we get a chance to review, review the test, review, any potential failures and then the ones that have question marks or nothing we haven't. Yet nobody has taken on those yet so we're. Essentially, this is the way that we allocate the work across the organization yeah.

E

C

Spring, we usually try. If you see better one I better to be better to be came out, we usually try to fill those ones that were already present in the preview to keep up with better three. So, for example, this is all your toolbox and has the question mark has more it's more important than adding, for example, arcade, which has no bindings just yet for Xcode 11, sorry, if I interrupted, but it was a nice detail.

A

Okay, so those question marks are like we: we think that there's something in those changes or there's other just no PR yeah yeah got.

C

It there it means that no one took it, so no one took ownership of doing it, but we do know that there is add it. So if you click and b1 b2 b3, it will tell you to death a little there. You can see all the differences in the Heather's I see.

A

So if I'm coming in, if I'm coming in and I download, the preview I can say. Oh, this is against preview too. So it may not have anything for app kit yet because there's no PR done on it. Basically right.

C

Conicelli, if you see you see, for example, the one that was mentioned by miguel authentication services has been updated up to two three and if you want to find out, if you landed, you can click on the PR and probably well I think it's merged. So, let's convert to this one. So you can see obviously the changes that happen and usually the better the smaller the changes.

C

Obviously, if we, for example, have something like AB kid, where it has no PR seriously, you're gonna have a larger PR because we're gonna try to get from one to three in a single PR. So, ideally, if you want to know hey, is that spring were supported in the preview quick way to do it, it's getting to the wiki.

C

Also, if you want to contribute with frameworks, it's also very nice way to say: okay, I'm, very interested I'll enter in contact, CI or choreo audio, and so I want to take a look and see how I could do the binding, which I'm gonna. Let Eric explain how it works. You can easily go to the week and say: okay, I'm gonna pick up Cora. You know I'm gonna, see what the other differences are his case.

C

They just moved to Heather, so you'll see that there's a lot of noise, some kinds of the dates, because either you're moving Heather's from one point to another one or you're changing availability, so they change the attribute or the Mac Packard I, just tell you it's available on iOS or available on iOS and support, so I'm gonna.

C

Let Alex play more or less what the process of creating a binding, because it's not as scary as it sounds and I think that a lot of people think that we're doing crazy, PE books and and also really like you Lolo stuff. But we are not in that point, which it's a lot easier, so Alex. If you want to take over.

D

Sure, oh I'm sure my screen, yeah.

A

I think this is cool, because I never really realized of how much detail on that Wikipedia page is actually available at any given time. Maybe it's just me being naive and not going to wiki pages on github ever um but I like to actually see it being used and then going through and like actually being able to track. Every single change is like really helpful. So that's really cool yeah.

D

And also something that I would like to add to model explanation is that you don't actually have to wait for the previews. If you go directly to our Xcode 11 branch and click on comments, if you want to get into the latest best bits, you can just click on the red closes and download the summer in Mac or somebody aus package. Those.

A

Are the packages are there in the in the up in the commits? Yes, so.

D

As long as it's merged you'll, you should be able to download the packages, so this is really handy, but.

A

That is like the at your own risk. This is, you know completely rare, like you know, there's you know been it's been merged, but it's not like in an official release. It's like go to town go for it. If you want to live on the edge type of thing. Is that accurate, totally.

D

E

There's so many tests that pass, you know the first of all all of a regular test past when we do these merges there's the human validation that also takes place, but also we have built frameworks that compare our internal use of the API against the public API, just to make sure that we don't violate any rules from Apple. We scan for coverage for completeness, so so the reality is that these bills that you get out of here, they are pretty good.

E

So it's not the I mean this have been we've built so much infrastructure to make sure that we eliminate as much human error as possible that that yeah I mean this is what I typically use I just want download one of these puppies myself.

C

Well so, like you show earlier, you can see that we were running all tests, also in a real device, with the aisles better, that's of being under deep element say so: we've tested the eternal device it won't, they won't catch fire. Oh.

E

D

That's right so yeah. Basically, they are good to go so, okay. What I wanted to know why I wanted to do before actually going into the binding process, since we were talking about community contributors, I want to give a big generating content.

D

He has been contributed contributing to a repository for the last month, so we are really happy to get any kind of contributions, whether is directly into the code or to make or repository even cleaner. So please contribute come and also if you want to get to started on it, we have or contributing guide right here.

D

So you can follow the steps and you should be able to get some in iOS build from source, and if you have any questions, we actually hang out on break here, so you can join or chat and we will answer all your questions about Hill together or code running. You know.

D

So that said, I want to look at this pencil kit PR, which has been recently merged and what it has is basically the changes that Apple introduced it into this new framework. So what I want you to see in more detail? Is that this isn't gonna be a message sample actually, for example, this is currently okay and what Apple give us is it's it's a header and objective-c header right here, and what do you have to do is actually create, let's call it our own header version, but in c-sharp, and it's based on Caesar interfaces.

D

So we really do is in map the objective together into a seashell representation of it. If you see, which is to interface, similar action, which is the actual name of the objective-c object, and we have the same name here in c-sharp, we see that it has properties right here. So in our descriptions, a short description file, we have the same properties with these attributes on top that actually mapped from the C sharp name to the actual Objective C name.

D

So what what you basically do is Mount these to blend these two sister files and we will take this file and actually, as model said, generate the actual interoperability code for you. So you don't have to write all these scary code by yourself to call introspective C so.

A

You take kind of like when you're like, oh I'm, gonna go, take a car play, for instance, and there maybe is a diff, maybe added a single new API. So really you just add a new API or new property into it and then there's automatic stuff that happens like so. The on the right-hand side that stuff's done manually is that what you're saying and then the craziness is all Auto generated, correct, gotcha and then so all those little attributes like no watch no TV or whatever those are all kind of samurai.

D

So correct and you can find documentation about that. We can post a link say here in your binding Objective, C libraries documentation. There is a complimentary guide dude this one, because this one actually introduces you into the binding process. So we have this binding x reference guide, which is the actual documentation on what does each attribute mean.

D

So, for example, we have base type here and we have earlier explanation of what base that means so yeah. So basically you have to go to treat this to these two documents and then you should get a little understanding. However, binding full binding process works. Well,.

A

I guess the nice thing is that sin all of iOS is bound already. You could literally just take one of them like look at what this car plate one is, and then it's probably very similar right. You know kind of as new api's arise.

D

Correct yeah: it's for new frameworks is where the big chunk of work is, but for existing frameworks you can't just like, like I, said they I just added a bunch of new objects or new properties. So it's it's easier from an existing framework point of view now.

A

Is this all have to be done manually or is there some like generator tool in general, that can kind of like help out if people are getting started.

D

So we have a tool called objective Sharpie, which you can actually find here in the binding headers. This is actually useful for actually this tool works not only for our bindings, but you can actually throw any third-party library that you want to bind to it and it will give you a starting point. It won't get. It won't give you like a hundred percent.

D

Like abiding project per se,.

B

D

If you give you something for you to work on, you know it will, for example, here it will give you. This is a starting point: the output of objective sharpie, but you have to come and make a more sister, friendly API by yourself like, for example, you can get any it with title style, Handler and then the name will be something like in it with title and.

B

You don't want.

D

You want something like create or get title or you know, I, don't know if that makes sense, so objective Sharpie. It gives you just a starting point: got.

A

It okay, it's gonna, be like a loose translation kind of correct.

D

But it's pretty accurate because since we have to go from the manage to manage side, do you can rest assured that this information, which is like the critical information that we need to interrupt with objective-c, will be correct, so objective sheppy will output that information correctly? All you have to do is make that interface file more seizure, friendly gotcha.

A

C

Like like, following what alex says, we don't only rely on that. What we usually try to do is, if there's, for example, there it's a very common thing in you know, which is we take an NS dictionary with certain options right and those options are a constant and a string and some value, and usually that values and NS object, and you don't know anything about it and and that's a pain in the ass.

C

If you were a dotnet developer, because you want to have like a nicer API, so, for example, we create what we call strong dictionaries where, for example, we create a object with classes that will allow you to have properties to set to diabetes and then, in the background, we convert internet a dictionary. So, for example, you work I know you going to do something with all your tools which are being working on recently. There are certain things: I have to pass for the buffer to work and that in and that's a pain in the ass.

C

If you get the NS dictionary, because you need to know which key you need to know, what kind of value goes in that key, so if you go to or all sources, you'll see that a lot of times we try to clean out that stuff, because it will be an honor to be just passing random things. So we on top of the export and the availability attributes, there's a lot a lot of stuff that we we try to do manually. There's also certain classes that we bound manually I, think Alex can show a couple them.

C

So usually the pattern is, if you go to resources, you'll see this named CS, and that has the interfaces which I considered them as contract for the generator to write the code and then you'll see a directory with the same name L and there you can see or manual most of the time the manual binding is for very low level stuff that still using C the CF network, or you can see there, for example, the energy recession handler, which is what's passed to the exit decline, and things like that.

C

So if you like, if you want to say I, want to contribute to buying means, first look at those attributes or the generator to pick up and generate your frameworks and then later try to look at what we're doing in or manual diamonds, and also this is really interesting.

C

I, like the you know, the pipe on hand, because it's really interesting to look at the generate code is very interesting and you can see how we're sending messages to different objects and- and we making sure that we have like, for example, null allowed we'll make sure that we don't check against no pointers. Well, and you don't have the activity to out like that. You could show that because I think it's like the most interesting part, because the generator does a lot I think I'm a decent stuff.

D

Yeah, and also if you have any questions you can come to the pure channel, which I am and we would try to door based glance at them.

A

Yeah I think it's it's pretty cool, because I know that, like what was I doing recently so you're saying like right now, I know like when I use map kit there's a way there's like a dictionary of addresses that you need to pass them. I know in iOS, I think that has really nice like you can use the contact bindings to be like this is the the street name, the zip code and things like that I think in TV OS and our bindings are not there so like.

A

If I wanted to I'm a developer, I could just make a pull request for, like the API exists. For me to create the nsdictionary and put the hard-coded strings in, but like I could contribute the constants. Basically like. Is that a thing that could happen? Yes,.

C

And it's super easy and uh if you pull request, I'll be very happy to because because this, if you look at the headers it so much that that we try to your best and we try to be super fast, but sometimes we have to prioritize, and sometimes we make mistakes. We could you know they were humans, and even that we have. We have a lot and a lot of tests to make sure that things are working right. You don't have typos in the in the selectors and things like that.

C

Sometimes you know humans and we forget to do it in a platform or we didn't think about it. So, for example, I think that one of the really nice things of being open is that if you are interested in a framework- and you see that we're binding it, you can get your feedback about the API and say well, I, wouldn't do it like that in c-sharp, so.

B

C

We try to be very consistent. It's always nice to hear from people are gonna use the API I'd say yeah I, don't really like that property name or it doesn't really make sense, and thanks Adam and even it being feedback I. Consider it to be a contribution. The people soon be scared. Folks, I know I'm gonna, look at the framework because getting paid by also really welcome contributions. Also I make a lot of typos, so the one who didn't catch up those one will get me. Those.

A

Are my favorite pull requests all my open-source projects when someone just has a pull request and fix the typo and I read me or in my source code, like that's the best because I'll never catch it? You know what I mean ever.

D

Yeah, that's true. Yeah I'm, like what Manoel was saying about the dictionary types like ing james. Also, it's, for example. You can map the fields here from these fields that you get in Objective, C headers and provide actually strong types to them like string and you ID, and this is documented, so you can come here to documentation and actually see how to make it. The API even bed for your libraries. So this when we use this for the actual sameen is brother and Mac. It can also be used for third-party libraries.

D

So if you're, a library, bender and you have your objective-c SDK, you can totally use the same stuff that we use to make position library pleasure to use. You know. Yes,.

A

If you see and you're using an API and there's a bunch of Anna strings, don't come in here and then make those strings. Basically.

A

That's cause they're anything of the code that you wanted to show off the generated code, a little bit to talk through that in a minute. I was kind of talking about that or was there something else.

C

Yes, so how I know I'd like to see how the generated code for some quote are correctly and and say? Okay, we went from this interface to this January code and this is all the stuff that we're writing for you or is being generated so that people understand it's not black magic, there's a bunch of cold or dawn. There's a lot of stuff going on there and it's always interesting to look under the hood. If you go one nope and I think you did yeah yeah.

D

Give me a second: can you see my screen now top.

A

You're back to yourself, oh.

D

A

D

Okay can see that damn yep awesome, so we had these carplay binding right here, I'm going to go back to that one and the generated code for that actually class.

D

Let me see if I can do top bottoms, because the generated code is larger.

D

There you go so, for example, let's: let's look at an interface, EP alert action, so what the generator does it creates all these code and creates a class out of this interface definition. So this class is called CP alert action that inherits from nsobject, because that's what the base type attribute does it says that the default constructor is not there, so it's not generated and it implements the NS secure coding protocol.

D

So we give this representation as c-sharp interfaces, but what you can see it right here and let's look, for example, at the code generated by this property right here, which is title property, so Lexi.

D

Should be down here, style handle title okay, so the result of this property declared right here will be all this code like, for example, if you try to get a property and you are using 32-bit device.

D

We know that this is not present there, so we will throw an exception for you that it's not president 32-bit devices and what we will do is we will try to get an nsstring from the unmanaged code and we will send the title message to the actual class and the pointer that we get from this particular method called a meteor. A message send will get translated into an actual dotnet string instead of an NS e string, because in the manage side this is an industry but which is handled that for you. So.

A

It does kind of all the marshaling back and forth automatically it's a kind of what it's doing. Yes,.

E

Correct right, let me let me sure, let me share my screen, because when you look at this girl right when you're looking at all this stuff, it looks like oh, my god, every time I call a method. This is a lot of code. So let me show you what I, let me show you a presentation that I made a couple of years ago.

E

That shows how do I share this thing. I, don't share my screen so.

A

You should be, there should be like a little share. Little. It looks like a little wind looks like a little tablet with an arrow yeah.

E

I saw that, but then it's suffering me Microsoft game, desktop I guess can I do that's the per window. I guess I can do desktop. Yes,.

A

E

Does this work oh.

A

E

A

I see are they're linking to point. Oh yeah.

E

Yeah, so when you look at a piece of code that is generated like this one right, it looks like a tremendous amount of junk and let me walk you through what this is doing right it. This is taking one parameter to section: it's calling a method that returns a CG right. Then you see all this John Kay you're thinking good lord. What is what has happened to my life right, so what we did is that we made it another linker, compilers and in liners Trinity is into a very optimal piece of code.

E

So the first thing that we do is that we take care of the first. If statement, you see that big ugly, if statement that says is the direct binding, you.

A

Own a zoom in just a little bit more for us yeah.

E

And this- and this thing has to do perf- and this is- is related P early to whether your sub classing a method or not. So this is what allows us to integrate the objective-c object system with C sharp, so that do you have C sharp, has the same capabilities that object the C does so. This is what the the sausage that that is really showing you. That's what Alex is showing you and what we're gonna do. Is we're gonna kill this thing, so the first thing the linker does is is BAM. It kills that thing.

E

It knows exactly at compile time which one of those to code, that's our gonna, be executed, so we're remove the first chunk right. So this is actually what they're mom then the next piece is, we determine hey. Am I running on device, or am I running on simulator right? So this is something that we know executions time. So we choose one of those two code, that's BAM there you go so now that whole method and all that junk that is generated is down to two. Then we have this other interesting thing right.

E

Is this a 32-bit application, a 64-bit application right? We still have this with the watch right. So that's what it's checking the pointer size BAM right now we got two just one call and now we're down to the actual marshalling right, so we essentially made everything except the one call that is needed right, so that's very important to keep in mind and then, and they were of course gonna. Let the the the inliner do its job, but here's the next thing that we do you know a people can release Pam.

E

We remove Sophos debugging capabilities from the code, and then we noticed these cute little names like get select or get handle right. So this looks like a method call to the untrained eye right, but we've turned this into adopted intrinsic. So it looks like a method call, but what happens in reality is BAM.

E

In the native code in the native code we actually just inline a constant that points.

C

E

Pointer in the hip right so.

B

E

Ends up happening is that you end up with a single call right. You end up with a single call. This whole thing. This whole thing is a single method, call where you pass a handle, a constant and the number. That's it, and then the aliner does its job.

E

So if there's no, if the, if they're marshalling it's super easy, then that's it, you can leave it good into the caller side and you can go back to having a happy life right and then, of course, there's a whole linking process right so that we do in the library which which essentially you can serve in a very large application.

E

But as you enable linking, we essentially walk through all of your dependencies, and we only keep the pieces that you need right, and this particular example you're using those three balls on the left ride those three little balls of great balls and and I built together. What you need, we extract it and we end up with this very nice teacher trying on the right. So that's how linking technology works. Oh.

B

E

Just wanted to make sure that this didn't look scared that it actually is. We actually put a lot of work and effort into making sure that your application is as thin as possible and as performant as possible and, of course, in the end, we feed this through apples, LVM compiler, so that further in lines and optimizes the resulting code. So anyway, that's my my one take when you look.

A

You take you, can stop sharing your screen too. If you want to there, you go so I. Think what's nice is in general, like you have the bits that Manuel and Alex are talking. Abouts like hey like this is this is what Apple gives us. This is sort of the the small chunk of code that you have to write by recap this. That kind of then allows all the code generator and and and all that stuff to put out everything, that's possible right and then.

E

What, then, that all the linker stuff.

A

Goes in right exactly.

E

So our job is essentially to map the objective-c conventions to dotnet conventions, because you know there were a couple of efforts. I mean we're not the first ones that bind objective-c over the years. But but if you look at how, if you just do a simple mapping, the results are terrible. Then you know the api's are difficult to use they're not well named. They don't follow the dog at calling conventions, the naming convention, so you know it makes for harder discoverability for users right, so we're gonna have something that is consistent.

E

Without that on the naming side, then we also want to use some p.net types for interrupts right, so we're going to use dotnet urls over here that use dot, that strings and all that stuff. So that, essentially you can. You can interrupt more easily and the other thing that we do is we we want to make the API compose well with dotnet, and what I mean by that is, for example, collections will be ienumerable.

E

That means that you can for each on them or you can link over those properties. We want to make them return tasks. So any a thing: async method we flag it specially, so it returns an async, an async task. So that means that you can either pass a callback like you know like like people would do you know fifty or a hundred years ago or you can or you can just use async in a way right.

E

So so we make sure that not only we do the naming, but everything that would interrupt properly with the platform so that you compose these things or collection initializers that lets you use all the native api's of the Apple platform, with collection initializers, for example. Right. So that's the kind of work that we have to do and- and you know what part is naming one part is mapping, and there are other parts that where we spice up the API right and make sure that it composes well nice.

A

Someone was Rober is asking in the chat if those slides were from a private, like internal presentation of those publicly available publicly.

E

Available these are actually my slides. I have to find them right now, because I mean I just got scared. When I saw that screenshot, what is making it look horrible we put so much effort making is good. These are public slides from the dotnet conference, 2016 I'll.

A

Put a I'll put a link into the show notes on YouTube.

E

I can send you the PPT I mean it's all public yeah yeah.

B

E

Had this day, but you know, as we go into the you know: soda stop, there's, obviously, three years old so no longer applies. Oh my god. We're talking about about fated, sweet I'll, still relevant. So.

A

E

Relevant yeah we're still took a peek holes, not relevant, not relevant. No yeah.

A

Anyways, nice: well, is there anything else and in this release you want to you want to talk about, because I just noticed that the the blog post is up so iOS 13 preview release I'll, put that into the the show notes.

E

A

And boom I think.

E

The most important thing that we're trying to achieve right now and trying to when we looked at what was being worked on and what was not being worked on. You know you might think well, I know the working of this alphabetically or some other way and the way that we're prioritizing the work is anything that our developers will need to meet. The new requirements from Apple is what we are putting up front right.

E

That's why we got authentication services in there very early on, because Apple is saying: hey if you ever put a Google sign-in page or a Facebook page, you must add Apple ID right. So this is not a. This is not a suggestion.

E

This is a requirement right, so so our developers I mean everybody's gonna have to adopt this, so we're front-loading all the things that are mandatory changes so that you can get access on the early private previous to all of these things and you can plan accordingly. This is what we did this release this week. This is why you know, as Munro was saying earlier today, we release we'd better to an apple shortly. Instead of three it's okay, it still works no problem, but this is what we did it right.

E

We didn't want to hold back anything because we know that people need some of these api's right away. Their API is that we need now for multi window management UI, since if you have an iPad app, you must start using UI scene and lots of little things like that. So this is what we front loaded and we have a team of folks just going through the. What is the most urgent thing that that you, as the summer and user, need to start testing now and then we'll get.

E

You know, I think in a month you'll see that we'll start working on more of the happy. You know optional features and by the time we ship you get you'll get everything, but we want to make sure that you have enough time to prepare for the for the Apple requirements.

A

Yeah that make sense to me so in general, so I like that I like that I'm, you know people can can can get their get their hands on it right now. They can go and test it, especially you're right, because some people need the ability to get access to that stuff. But then I like that, Alex just show that there's you want something new, just grab it from the the pull request right and just grab the bits now I'm. Imagining here like what are the requirements for the iOS 13 preview.

E

What I mean requirements from like.

A

Do I need special visual studio, so I need special, Mac versions. Like you know, what's the requirements on this puppy, the.

E

Reality is you, don't need a new Mac version and unless you're doing Mac software right unless you want to use something on Catalina, but you know I'll tell you my horror stories of my Catalan experience another day, but I would suggest that you stay on Mojave. Unless you have a dedicated machine for Catalina. Ok, so stay with Mojave, that's the first orbit. Then you do need to get our previous by selecting the preview channel and on on Visual Studio for Mac and then and then you need to get Xcode 11 beta, 3G and.

A

I want to devil that one saw in Mojave yeah.

E

And we're gonna get the Visual Studio 2019 preview. You know the the tooling that goes with the Windows version. Soon out, we haven't completed that work so stay tuned, but for now do it on the back. Do it on Mojave and I think we can fill a show with my with with what happened to me. It's partly my fault. So I don't want to blame anybody else. You're.

A

Probably not the only when I was talking to Frank and he said: I had a machine and now I no longer have a machine, Thank, You Katerina. So.

E

Because I figure out how to recover all the data but yeah there's some there's some courageous changes in Catalina and and and the courage comes at a price. Now your data is there and I can help him recover it. But you know yeah yeah, you're, developing mobile apps. For now someone.

A

Was asking so we are showing like objective-c api's, right being bound, what happens with Swift only framers and are there actually Swift only frameworks from Apple.

E

There is one there is one. There is one called my god. I can read what it's called, but it's one of these new, a our library Oh reality.

A

E

So we will support it, not in this first preview, but we have a tool that we're very close to releasing it's a tool that we've been working on for a couple of years now and we haven't released it because by the time we're ready, I'll tell you what it is. It's called systematic, so so, if thematic, it's very neat because it works with binary files and produce binaries that work directly with with the Swift bindings.

E

But you might not know this, but sweep has not had a stable, ABI up until I think a couple of months ago right. So what that means in human is that essentially Swift was broken or tall every. You know six months to a year right.

E

So as soon as we were like okay, we're done a week later with be broken right, so Apple has finally stabilized the ABI, which means no more breakage and now we're just putting the finishing touches on it, and we should be able to ship systemic soon, so you'll be able to have access to the whole catalog of so if API is very soon very soon. I know.

E

I've said this before, but this time I'm in it I mean I, always meant it, but this time this time Apple has promised they won't break us again, so so I so we'll get it soon. Lovely.

A

Well, there you go Dennis there, you go all your answers, we'll definitely make sure you follow our blog, we'll, definitely always tweet out all the tweet out and blog all the awesome stuff we go and and John Mark says thanks for awesome for all the awesome job that the team does they super appreciates it so I know I do I'm excited too I mean I'm excited to make the iOS jump. This fall, I don't know officially I might be getting an iPhone 13 signing with Apple.

A

I have to say: James, you portray me as a party sent, but I mean I. Yes, I buy, I buy iphone, buy six packs, but I do own a bunch of androids and I. Do carry an Android with me every day, not today, because my kids is long story.

Thanks for all the great details about the bindings thanks Hawk says from iOS to gooey, CS love all the work that the team does so we'll have to do a show on on GUI see us sometimes that'd be fun.

E

Love deep dives and some of the interesting stuff that is coming to Android and iOS. Yes,.

A

Absolutely that's what the extent of sports weather, blogs for and also for the xamarin show and have all that the team's I do want to also mention here really quickly, but in my machine Miguel sat down. I watch this this building careers. It came out just this week behind the scenes with miguel. I was very good. 45 minutes well worth your time on channel 9 and the Microsoft developer YouTube. So that was a fun watch. Yeah.

E

That was, it was a fun interview. I, don't remember what I said, but it was a fun interview and I refused to listen to my boys. So there.

A

Was I learned even more back history of of you, obviously, but also of xamarin and mono, and on everything to because I knew some, but then I learned a lot more. So it's.

E

Like an elephant right, I mean if every time I sit down with with folks in the team, including you, everybody had a different view of what Zaman was right. So it's interesting to listen to the stories from every right. So you know Alex had a different view and RAL had a different views of a she had a different views. It's always good to hear all the all the sides of how things came to be no.

A

All right all right anything else from from you folks, this.

C

One mentioned killed: 32-bit applications on Mac OS. If you want to be ready for Catalina, because when we were going to the generated code that I remember, we didn't mention this: your 32-bit application and Kathleen. If you still have them on Mac I believe we did, a blog post do remember that's disappearing and we think rather look. Some worry was with my croissants and explained the reasons mostly Apple.

C

So please, if you want to be ready for Catalina, start working on that perfect.

A

Yeah I'll also put that link to the blog post from Chris in the in the show notes about making the jump I think we just did it not too much ago. Chris and David worked on that yeah you and that way you don't get that app is not optimized, but are you saying in Catalina won't even in.

C

Anyone even launch no even Xcode 9 for will launch in Catalina, so you can warn probably not the best time to say when you were closing the show, but like that's a that's another, never it's.

A

Good to remember, yeah, don't forget awesome! Well, thanks.
