My team has two green field apps that we started a few weeks ago. The leads on the iOS team and Android team both spent a week evaluating the new UI systems in each platform, SwiftUI and Jetpack Compose. The conclusion was that Apple made a huge mistake tying it the iOS version and effectively limiting updates and it's real world use for years at a time. Both leads liked the design paradigms, but we are only going to…

Yeah iOS is one thing as you can generally wait it out as Apple is pretty aggressive about upgrades there but on macOS I think this limitation has really killed it's viability, people just don't update their desktop OS.

I haven't done much programing as a kid and i'm just starting to learn Swift/SwiftUI through the hacking with swift course, interesting to read the comments here as I didn't realize it was so hated?

Seems fine to me for building apps but I don't really know enough.

Looking at the documentation, it’s just scary to jump in and put most of your effort on swiftUI

Yeah, the documentation isn't amazing... but the example apps and tutorials are great! https://developer.apple.com/tutorials/swiftui/

I'm really looking forward to what comes of it, but I have chosen to do my current major project in UIKit. A couple of reasons: 1) The documentation for SwiftUI, when I started (about two years ago) was awful . I was shocked at how bad it was. I believe that it has since improved. 2) I knew of no major apps (even Apple ones) that had been done with it. I already knew that UIKit was up to the task, and held my nose, w…

Yeah UIKit is deeply MVC. It may not be the most conceptually elegant but in my experience you're almost always better off cutting with the grain of the underlying platform's abstractions instead of trying to superimpose a new leaky abstraction on top of them. I worked on one large iOS codebase that went all in on the VIPER architecture and it was one of the most unweildy and baroque codebases I've ever had the misfo…

I'm doing an app integrally with SwiftUI, as always happen with new frameworks, if you stay in the happy path everything is nice and easy, but if you start tweaking things, you are lost in the forest really fast.

To give you an example, it's quite easy to add the swipe to delete function (within a list) just adding .onDelete() but if you want to add swipe to delete to a LazyVStack (similar to a List) you need to implement the gesture detection and a few more things [0].

From my POV, SwiftUI IS the future, declarative UIs are awesome, I'm confident that Apple will reach a point where all the quirkiness are mostly gone.

Has anyone gotten SwiftUI previews to work at all with a project that has more than 20 files or some dependencies? My project utilizes Firebase as the backend and as soon as you add that dependency - SwiftUI previews never compile, due to build time outs.

Are you using MVVM and mocking out your ViewModels?

Is anyone using this really? My team is pretty excited about using it but I've been a little more hesitant mostly because I've not read of anyone using it at any sort of scale with success. Even for smaller project it still doesn't seem production ready.

It is frustrating at times, but I like writing UI in code and it increases my productivity quite a bit. I’m using it to build an IDE (https://austinrude.com/devlog/zig-ide-2022-04/).

I don’t think I would have attempted a project this large without it. I had to fall back to AppKit/NSViewRepresentable for the tabview, text editor, and a couple other views. There are probably over a hundred SwiftUI views though. And I am hoping I can switch the tabview to SwiftUI after WWDC so it’s easier to extend.

About WWDC, I wonder if we’ll see a CoreAnimation replacement this year that is exposed to SwiftUI views? I don’t know what the implications would be, but it makes sense when you look back at how they’ve refused to offer/expose the underlying UIKit/AppKit APIs that SwiftUI is wrapping for some controls.

Earlier quoted context omitted.

When you support a range of tools, or introduce a new one, you often do it to support different audiences. I'm not an iOS dev. Is it a case that SwiftUI is really intended for a different audience and set of use cases with no expectation of a 100% overlap with the UIKit use cases?

It's marketed as a complete replacement of UIKit.

Trust me, noone at Apple believes that. Not even the SwiftUI team.
