You could always use instancetype to indicate that you're getting an instance of the class back.
@interface NSArray (XXHelpers)
-(instancetype)reverse;
@end
or even better
@protocol XXReversing <NSObject>
@required
-(instancetype)reverse;
@end
@interface NSArray (XXHelpers)
<XXReversing>
@end
@interface NSOrderedSet (XXHelpers)
<XXReversing>
@end
