How hard would it be for Apple to make SwiftUI, SwiftData, and AVFAudio support Linux
So that we can hopefully get some cross-plat efforts going... I've gone ahead and separated out all the cross-platform-capable code into a separate Swift Pacakge called SwiftRepoCore. That represents 37% of the total app—all the 'business logic' from macOS app that I could feasibly separate out... almost all the state machines, actors, data models, and services.
SwiftRepoCore has the following dependencies, both of which are cross-platform:
-SwiftXState (2.0 alpha, which adds the SwiftUI-like declarative state machine DSL) Note: SwiftXState also depends on swift-docc-plugin but it won't use it for normal builds when it's a dependency. It's just there for building the docs on CI.
-CompositionalInit (a very lightweight lib that came out of an old evolution pitch here, which adds "CasePath" and KeyPath-based initialization and functional cloning with mutations, used by the state machines to make targeted updates to state, without relying on any macros).
That leaves 5800-ish lines of code that need to be ported to create a linux/Windows/etc. version:
- the SwiftData/SwiftUI code (we could omit the configurable colors/fonts; some of the eye-candy elements; and all the data persistence while still a functional app)
- the Apple-specific audio API code from the music player lib Ox0badf00d (totally unnecessary to port at first)
If you feel like giving it a try, fork the main repo and start working on a Linux UI port. @codelynx posted back in March that they have made a Linux port of SwiftUI. The app does not use anything fancy in terms of UI, so it should be pretty straightforward to make cross-plat.
I'm pretty useless when it comes to linux development, but if you're not wanting to work on that let me know, I can give it a shot.
