To which dispatch system does the @Objc Final annotation in Objective-C belong?

The @objc final annotation in Objective-C does not directly relate to the dispatch system.

@objc is used to expose Swift classes and methods to the Objective-C runtime to ensure compatibility between the languages. The final keyword in Swift prohibits inheritance from a class or method overriding.

Thus, @objc final means that the class or method is accessible from Objective-C but cannot be overridden or inherited. This is not related to the dispatch system but rather to inheritance management and compatibility with the Objective-C runtime.
