Can Swift 1 code run on iOS 9?

Question

I was wondering if anyone knows whether or not Swift (version 1) Code will be able to be run on iOS 9, or if the syntax will need to be updated to allow it. I'm assuming you probably don't have to update the code, but if anyone has any opinions please do share!

Answer 1

Xcode 7 will ship with a Swift Migrator tool (similar to the Swift 1.1 to 1.2 migrator used in Xcode 6), which will help developers migrate Swift 1.2 projects to work with Swift 2.

Projects written with Swift 1.x in Xcode versions previous to 7 will run on iOS 9. Any projects written with Xcode 7 must use Swift 2.
