Swift is absolutely cross-platform. I've used it a lot on Linux. I think I even prefer it to Rust for things like server applications.

I think Swift may even be available on Windows now. But it's definitely available and rapidly maturing on Linux.

And having struggled with large code bases in dynamic languages for years, I'm very happy that statically-typed languages are resurgent now.
