I've seen on the swift-evolution git repository README.md page that Portability is one of the design goals for Swift 3.
Does this mean that Swift 3 will be available and useful on Windows too? So that it could be used for cross platform app development on both Windows and OS X (and probably also Android)?
For example, will Swift 3 be able to interoperate with Objective-C on Windows (e.g. using GnuSTEP or the WinObjC bridge from Microsoft)? Maybe using WinObjC+Swift on Windows, GnuSTEP+Swift on Linux and Native-objc+Swift on OS X? Such an application could probably share very much code between different platforms.
