Xcode 6 Auto Formatting messes up Main.storyboard on iP5s... any way to fix?

I'm messing around in Xcode 6, trying to develop a Single-Paged Application for a class. I know VERY little code, and whenever I try to re-adjust the Auto Formatting in Xcode, it doesn't appear to work. The app gets cut off and only displays a fraction of what is on the storyboard (My guess is it has to do with the iP6/iP6+ resolutions). I'm coding in Swift for iOS 8.1. Thanks for your help!
