About a year ago, Swift on linux was a bit of a minefield. Only parts of Foundation were implemented, and you couldn't use the Linux toolkit on a Mac to cross-compile or even just link against the Linux version of Foundation. The recentish move to reimplement Foundation in Swift natively is a big win, and I haven't tracked how close that project is.
