swiftenv VS Tokamak

which is at most half-truth cause this is just official installers and most likely you'll use some sort of rustup (which wasn't official few years ago) you can use https://github.com/kylef/swiftenv you can use community packages https://wiki.archlinux.org/title/Swift etc.

"and so on is that languages other that swift aim to support linux in general." -> again not true linux distro dosen't change swift usage it is just official build is run for few most popular distros and you can use prebuild swift-bin on any linux repo. (arch, debina, ubuntu, centos etc. etc.) You can say the same stuff about rust/nim/go every other language that didn't have official release for some niche linux distro.

One disadvantage of Swift is how Apple decided to deploy new versions. They only come bundled with new versions of their operating systems. However, with swiftenv (kylef/swiftenv) other versions than the bundled one can be installed. So maybe that adds a possibility to run more modern swift versions on older hardware?

I’m also working (slowly) on native Flutter channels:

But this is really targeted at embedded use cases.

There is Tokamak but I don't know how usable it is just yet.

TokamakUI runs via SwiftUI on WASM for web. Apple just hired the creator of the framework.

You can even make web apps by creating web components in swift with Tokamak.

I am playing around with Tokamak just for a bit of fun and learning, and it's been pretty solid so far! Though I want to branch out and play with some dynamic data from a random API, instead of just using mocked/pre-populated data.

There is SwiftWasm that compiles swift into WebAssembly so you can run it in the browser, but swift can't directly manipulate the DOM so you'd still need JavaScript or something like TokamakUI so you can design the front-end portion of your app.
