It is often impossible to get away from needing at least some of NSObject's functionality, but fortunately you can declare that your protocol inherits from another, and there is also an NSObject protocol that defines the core functionality of the class, so you can do this when you declare your protocol and never need to worry about "NSObject<someProtocol>"

@protocol SomeProtocol : NSObject
// stuff
@end
