Objective c protocol generics

Can Objective-C protocol be generic?

Following this tutorial, I'm basically looking for something like that:

@protocol ItemsStore<__covariant ObjectType> <NSObject>

-(NSArray <ObjectType> *)items;

@end

Which is a generic protocol for some ObjectType that "implements" ("inherits") another protocol NSObject

Solution

  • As @rmaddy suggested, and as referred to this questions, it is NOT possible. Shame, moving to Swift then...
