xcode 7类型的参数不能应用于非参数类。

I'm getting this error in my xcode project today... I have never got it before. The only change I've made since the last successful build is that I imported the iAD framework (I did that this morning before I tried to do a fresh build, so I'm not sure if it had anything to do with it. I doubt it though.) All of the issues are with NSSet/NSArray/NSDictionary and are all contained in UIKit's UIEvent and CoreImage's CIImage. If anyone has any idea what might be going on here, I would appreciate the input.I'm getting this error in my xcode project toda
