Tokamak

There's a couple: https://github.com/stackotter/swift-cross-ui (Linux + Windows) https://github.com/TokamakUI/Tokamak (WASM + MacOS + some Ubuntu support) They both had to rewrite the entire backend from scratch, because SwiftUI is very, very closed source. But Tokamak does have an import that just forwards to SwiftUI on Apple platforms.

There's not a consistent story but there are a bunch of options, principally divided into wrappers around existing libraries (SwiftGTK [1], Qlift [2], LVGLSwift [3]) and SwiftUI workalikes (Tokamak [4], SwiftCrossUI [5], AdwaitaSwit [6], there are others too). After exploring most of these for my use case (something that needs to run on an "embedded" RPi CM4 as well as iOS), I wrote a Swift bridge/runner for Flutter [7] which is working well. That enables me to write the UI in Dart and the business logic in Swift. I looked at all the other options below (that's how I know about them, indeed [3] I wrote as part of my research), in the end I felt that none of them were at the time of investigating sufficiently mature to base a product around.

Other things worth checking: https://github.com/stackotter/swift-cross-ui https://github.com/TokamakUI/Tokamak I’m also working (slowly) on native Flutter channels: https://github.com/PADL/FlutterSwift But this is really targeted at embedded use cases.

Any relation to https://github.com/TokamakUI/Tokamak?

Some interesting stuff happening here [1] and here [2] too. [1] https://github.com/stackotter/swift-cross-ui/tree/main [2] https://github.com/TokamakUI/Tokamak

Tokamak[0] is really promising on this front [0] https://github.com/TokamakUI/Tokamak

I’ve been seriously impressed with Tokamak for Swift. Is this what you mean for browser native GUI? https://github.com/TokamakUI/Tokamak

I wonder how far you could get using something like https://github.com/carson-katri/SwiftWebUI or https://github.com/TokamakUI/Tokamak to render the Swift app to a webview for the other platforms... I’ve not tried it, I imagine there might be jank and limitations as SwiftWebUI is “a toy project” but with some work could be a legit option - I’ve run pretty bespoke and complex React Native applications as desktop apps via react-native-web and Electron and it worked incredibly well. I do like the idea of only maintaining a single codebase, but of course it comes with significant trade offs. The idea of building for Apple-first but automatically getting a reasonable fallback for other platforms is quite appealing - as you say, for many businesses it probably makes sense to focus on having the most polished iOS experience possible. Honestly I’

I'm excited about a few projects bringing Swift to other platforms. SwiftWasm is surprisingly painless to get working [1]. Tokamak is an early stage SwiftUI-compatible framework for building web apps [2]. It also has the goal of supporting other native platforms and to that end there is early work on a GTK backend. I have no affiliation with these projects, though I would like to contribute to them at some point. [1] https://swiftwasm.org/ [2] https://github.com/TokamakUI/Tokamak
