Leo Dion (Host): Welcome again to another episode of empowerapps.Show. Thank you for joining me. I'm the host, Leo Dion. This is the BrightDigit podcast where I talk about Swift development, development in the Apple ecosystem, and just overall updates, changes in ways that managers, CTOs and developers can stay current and up to date with new things coming out when it comes to Swift and Apple products.
[00:00:36] Today, I'm going to be talking a little bit more about SwiftUI - the good, the bad, and the benefits. Specifically, I want to talk about my experience and examples of work that I've been doing in SwiftUI over the last few months, and then we'll be getting into why Swift UI is here, why Apple introduced it in 2019 we'll then be talking about why SwiftUI is not really a good use case in a lot of examples. I'll be talking about some workarounds about how to get around that if you still want to use Swift UI. And then we're getting into when and where Swift UI is the ideal use and what apps or maybe devices, where Swift UI really makes a lot of sense.
[00:01:21] So I want to talk a little bit about my experience and examples of where I've been using Swift UI.
[00:01:27] So back in June, I actually did a workshop, and while it was the same month as WWDC, a couple of weeks actually afterwards, I ended up using UI kit for it. I called it PeoPart because that's the random name generator - what it came up with. Essentially, it's a list of blog posts and comments that you can see on an iOS app.
[00:01:50] I use UIKit for this example. Because at the time I really didn't want to jump into SwiftUI with new developers and risk that. But I will say that with this application I am slowly migrating over to SwiftUI. So the sample app actually available for you on GitHub and they will share a link for folks later in the show notes.
[00:02:16] But this is a example that I want to see what it'll do and what it will take to convert a UIKit app over to Swift UI and see what exactly happens when I do that.
[00:02:29] he other example is a app that I'm using or a building for my local coding community. Lansing codes where people in Lansing can see what events and what meetups are taking place.
[00:02:43] It uses the Firebase backend and Web API that Eric, my colleague had built for the local community and uses combine, obviously along with Firebase. It uses Swift UI and I think it's a really great example of where I'm taking a fairly simple app, brand new, basically new app and building it into a iPhone app in this case.
[00:03:09] Lastly, you probably heard, I've been working on an app called HeartTwitch ,an independent watch app. They use a Swift UI and Vapor as the backend, and the idea of this app is that live streamers can share their heart rate right from their Apple watch and then take that sharing to a web browser window.
