I don't have any write-ups from myself. I was planning on eventually posting something, I have a lot of notes to sort through.

You can find some info by searching, there has been a few attempts to get it running on Android. Also just searching around github will net some other attempts.

The foundation dependency is the biggest problem. You can check out https://github.com/apple/swift-corelibs-foundation which gets rid of the objc runtime dependency for other platforms, though you will find yourself writing implementations for each eventually.

I would say if you are going to stay with just Android/iOS to look into maybe moving to Kotlin or C for your common layer and then call it from Swift. Kotlin multi-platform also has been improving recently.

EDIT: Also look at the Swift github, there are some docs about different platforms. https://github.com/apple/swift/blob/main/docs/Android.md
