Apple exposes their C/Objective-C enums in Swift without the usual
prefix, example:
Objective-C:
enum {
NSOrderedAscending = -1,
NSOrderedSame,
NSOrderedDescending
};
typedef NSInteger NSComparisonResult;
Swift:
enum NSComparisonResult : Int {
case OrderedAscending
case OrderedSame
case OrderedDescending
}
