I made an open-source project that will take an existing macOS swift project and make it easily compile into a Linux (GTK/ or Qt). It's part of a new quality Swift-first OS I am making called QuillOS.

I'm eager for help and for feedback.

Also looking for people who have Swift code (there is very little open source swift code) who can give me example apps to compile against this to find any missing holes. The simpler/smaller the better but any size good.

It's also easy to convert any working iOS app and adapt it to macOS with Claude, and then also cross-compile to Linux with this.
