I'm trying to make an app in Swift 1.2. Obviously, Swift 2.0 introduced a lot of changes but before I migrate the whole project over, I would like to be able to test it while being still on 1.2. But my iPhone is now running iOS9.1 and my Xcode 6.4 doesn't seem to recognize the iPhone for me to test.
Is there any way to run my Swift 1.2 project on my iPhone running iOS9.1? Or do I need to downgrade my iPhone in order to test the 1.2 project?
