Doesnt work with XCode 9

I installed to an iOS 11 project using CocoaPods, but there seems to be a problem with the NUIPGrammar and it's associated category definitions in XCode 9.

I dont think it likes having new property variables introduced in a Category.

Not sure of all the details, but for now this does not work with the latest iOS.
