SwiftWebUI VS swift-win32

SwiftWebUI - A demo implementation of SwiftUI for the Web

I have seen a couple projects with people basically re-implementing SwiftUI for other platforms (like SwiftWebUI). So it’s technically possible in that respect.

Im am just going to leave this here... https://github.com/SwiftWebUI/SwiftWebUI

You may be interested in this project which allows you to program with SwiftUI on the web. You can try it here.

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.

Even Microsoft has someone dedicating their time to building Win32 support.

Swift does run on windows now. There’s also a package that lets you use Win32 to write GUI apps (https://github.com/compnerd/swift-win32). The core code (data models, networking, etc) can be common, but UI will have to be different (Win32 on windows and AppKit/Catalyst/SwiftUI on Mac)

As others have mentioned, UIKit is an Apple framework and not available on Windows, though you should be able to use the Win32 APIs to build out UI interfaces. Alternatively, you can experiment with https://github.com/compnerd/swift-win32 for a nice layer on top which abstracts out some of the details of the Win32 API. Unfortunately, that is not as fleshed out as one would like to build complex applications, but that is something which more usage and work on library should be able to resolve.

For native apps, there's this, which gives an AppKit-like interface to build GUIs.

If you’re looking for Windows first projects with Swift, https://github.com/compnerd/swift-win32 is pretty cool.

Also check out this project by a member of the Swift core team, which is a set of bindings for the Win32 API for Swift on Windows.
