10 1,065 6.8 Swift

A Windows application framework for Swift

Project mention: Swift for windows - current state and how to get aboard | /r/swift | 2023-05-28

For jumping abord, there are not very many frameworks for UI development. There is https://github.com/compnerd/swift-win32 which is less WinForms and more Common Control based. There were a couple of different attempts for WinRT to get XAML based UI systems. There was no official support for UWP, and that would likely require some tweaks to the runtime.

swift-cross-ui

3 478 8.5 Swift

A cross-platform declarative UI framework, inspired by SwiftUI.

Project mention: Writing Gnome Apps with Swift | news.ycombinator.com | 2024-03-27

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).
