swift-cross-ui VS Relm4

For another SwiftUI-like wrapper, see also https://github.com/stackotter/swift-cross-ui (used by Adawaita to generate widgets, and mentioned in other comments).

The key premise of this approach is to provide a SwiftUI-like declarative wrapper around Gnome functionality. It's unclear what it adds over swift-cross-ui.

SwiftUI itself has growing pains mainly around being on the right thread for processing/updates and getting data binding right.

Blog entries on swift.org or from Apple tend to be little demos that show the happy path, but when discussing new frameworks (like a Gnome wrapper) or platforms (like the recent embedded), I'd like more demonstration that the authors understand and address key issues and will sustain development. Cross-platform UI frameworks get complicated quickly and have a long tail of issues (cf Flutter, Java/Eclipse, et al) that can be blockers for clients/users. For Swift it doesn't help to have multiple concurrency models and obviously different behaviors on apple platforms and Linux (where UI is not officially tested).

Some interesting stuff happening here [1] and here [2] too.

There is Relm (https://relm4.org/). Which is in Rust is just GTK (through it's Rust bindings) with a nice reactivity layer on top.

I’d recommend you checking out https://relm4.org if you know a little Rust. Relm4 is currently the easiest and most intuitive way to write GTK

Relm4 might make your migration easier. It has factories which make it easy to create lists (both sync and async) and recently added TypedListView as another useful abstraction over pure gtk-rs. There is a lot of potential in Rust + GTK, you just have to find idiomatic abstractions.

Did you try Relm? It's an implementation is the elm architecture (think react) on top of Gtk. Given your experience with Gtk it might suit you really well, as you can even take only parts of it and continue using bare Gtk for the rest. Give it a try!

What about relm4? Is it generally feature complete? Can one use relm4 for most things, and drop to gtk4 for the oddball task that is not supported?

Using this example: https://github.com/Relm4/Relm4/blob/main/examples/simple.rs

What advantage would this Rust crate have over Relm4? It seems pretty similar to me, save for the property based syntax that Forte has, instead of the set_* ones used on Relm4.

If you like Rust I recommend Relm4, one of the best experiences I’ve had with a framework tbh, be sure to learn gtk-rs first.
