Arc, TBCNY's browser for macOS and Windows uses Swift [1] [2].

Their newer Dia browser which is meant to be cross-platform also uses Swift.

> What company is using Swift outside of Apple-specific development?

Skip allows to "Build truly native iPhone and Android apps with Skip" so technically skip runs swift on android which is outside of Apple-specific development.

They also recently got open source from their closed source model prior from what I can tell

Doesn’t affect the validity of your comment whatsoever, but there was the attempt by the Browser Company to implement Arc on Windows in SwiftUI lol

Not a lot, but has absolutely no relation whatsoever to my comment.
