Xcode 5 is behaving just fine, and I\'m able to build and run apps on my iOS 7 device and in the iOS 7 simulator.
However, I do want to support iOS 6.1, but I don\'t
This might help u out better..you have to copy paste iPhoneOS6.1sdk folder. This is for SDK, similarly instead of iPhoneOS.platform select iPhoneSimulator.platform and then the same path.
