Earlier quoted context omitted.

I bet it's going to stay relatively the same, for now. React Native still works across iOS and Android, which is one of the key features. SwiftUI is iOS only.

It's my understanding that a lot of the appeal of RN is also that it allows web devs who are fluent in JS to make mobile apps, so I guess that's not really comparable in SwiftUI either.

I'm not sure about that. SwiftUI code looks an awful lot like React code. And IMO (as a web dev), it was always learning the UI framework that seemed like it would be the difficult part of learning iOS dev. Data manipulation APIs are pretty similar in most languages, but learning a new UI paradigm is a pain...

I didn't catch it. Is Xcode 11 (beta) available already? Do I need macOS Catalina (beta) to run it? I seem to have missed the crucial information and cannot find it on apples developers pages...

I’m one of the engineers that spearheaded this initiative inside of Apple. I just wanted to thank the HN community—I’ve been reading HN for 10 years now and it’s been formative in my development as a software engineer. If you’re at WWDC stop by the labs and say hi!

How would you compare this to React.js? In particular, how does SwiftUI approach the concepts that Redux solves [EDIT: in other words, state management]?

Redux and react are two different questions.

.color(.gray)) What object is .gray acting on?

That’d be standard swift type inference. The .color function takes a single unnammed parameter of type Color (or similar, idk exactly). Color.gray is a static constant value. So .color(Color.gray) can be simplified to .color(.gray)

To me this looks very similar to what Google is doing with Flutter.

Jetpack Composer you mean. I bet by next IO, Flutter will get replaced by it, specially after the #KotlinEverywhere announcement and Kotlin/Native effort for iOS.

Flutter is cross platform. I looked for it but didn't see where jetpack has this capability. Please post me a link if I’m wrong, I would follow this project if it does support cross platform development.

This is incredibly awesome! Did you get inspired by the web or by new frameworks like flutter?

Thank you, but that's how far I got myself. It is telling me there are no downloads available at this time. I am asking, because I am still on 10.14.5 and I thought the Xcode 11 beta might only be available on the 10.15 beta.
