On: Chris Lattner on Swift

[m0nastic]

Not that it's particularly complicated, but they mentioned yesterday that the updated version of the WWDC app (which they released right after the keynote) is written in Swift.

I don't know if that means "entirely written" or some parts, but they at least called attention to it.

Which implicitly means that swift code can be compiled for iOS 7. Which isn't surprising since the compiled code uses the ObjC runtime.

Swift code compiles and runs on 10.5 and up. Tested it myself.

When they talked about the WWDC app being written in Swift they also explicitly mentioned that Swift will run on iOS 7 and 8 as well as OS X Mavericks and Yosemite.
