Same model as Flutter which is a million times more pleasant to write and mature at this particular use case which I don’t actually think Rust is well suited to generally speaking.

I write both swiftUI and flutter daily. I think SwiftUI is the winner if we're going to put names forward. But arguably, not cross platform. But in terms of language adaptability for UI, Swift is king.

I would say the opposite and it sounds like a personal preference at which point I think lack of cross platform compatibility ceases to anything else other than a major major problem.

I didn't explain myself well. The point I was trying to make is the language of Swift is far more flexible than Dart. And in terms of UI implementation, it then looks a lot more like a DSL.

Because () are optional and a function call can look like this Button { stuff }. Meanwhile in dart, it's lines, and lines and indentation of 2 because it becomes a massive manuscript. I hope that makes more sense.

I must have a very different understanding of the word "arguably" than you. To me, it's arguable whether Swift itself is a viable cross-platform language today. SwiftUI, on the other hand, supports literally zero devices not manufactured by Apple.

Is it really arguable that when people say "cross plaform" when referring to a GUI framework, they aren't counting "both macOS and iOS, but not any of Windows, Android, Linux, web"? It might be accurate from an pedantic standpoint, but I have trouble imagining a context where someone would bother using that phrase as a qualifier if they understood it that broadly.

Rust's definitely well-suited to writing the low-level infrastructure pieces (the implementations of the renderer, layout, text, etc). You really want something with fast and predicatable performance there. Whether it pans out for writing actual applications we'll have to see, but a lot of big popular applications are written in C++ which is surely less suitable.

Yeah but sometimes you don't want to write connectors between high performance code and convenient to use UI code.

I welcome this, I want to write cross platform lightweight UI applications without going to C or C++.
