I usually start learning a new programming language making various GUI programs, maybe using a library like SDL if needed. But I can't seem to find anything like SDL for swift on linux! Most beginner resources assume you're using XCode on a Mac.

Or does Cocoa work on Linux too(last time I checked this is highly not plausible)?

I also have an http server setup with swift & docker:
