[swift-evolution] Swift 3 and cross platform development

Hi Michael,

This topic (in a form) has come up on list before.  It's my understanding that the portability that is targeted is core Swift, not so much Obj-C interoperability.

That said, there are a few people working on Swift for MSVC, and Swift already works with Cygwin.  Someone has considered making Swift work with an open source implementation of the Obj-C libraries (I don't think it was GnuSTEP), but I haven't heard from them in quite a while.

I hope that helps.

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.
