Add support for Swift language
Swift language is now open source (see swift.org). It's good moment to add support for at least compilation into .exe. It should also be an alternative to ObjC bridge as much more modern language. Both things can make cross development much easier.
I very much want this. I would love to be able to mix and match all my code and code in whatever language I prefer. As an iOS developer most of my source is Swift and objective C so adopting visual studio and supporting android and even windows would be greatly improved with this. It would be great for all of us
