Yeah but they expose the same ABI. If you can write in Objective-C, you could write it Swift and externally it'd be no different. And since they're reimplementing this stuff from scratch, I'm surprised they didn't just do that.

(I'm saying this as someone who would be more inclined to contribute if it was written in Swift.)

I imagine they are using either GNUStep or Cocotron as the basis for their Cocoa support, not starting fully from scratch.
