App won't run on iOS 6.1.3 because of missing GameController.framework (which is NOT used by me)

Are you building against iOS 9? See below:

Apple iOS apps run on the SDK they are compiled against and two older versions of iOS. So iOS 9 built apps will run on iOS 8 and iOS 7. If you need to still support iOS 6, you would need to build against iOS 8.
