Is it possible to implement inheritance from the Actor class to create its subclass?

In iOS, when it comes to the Actor class from Swift Concurrency, inheritance from it is not possible because Actor is a special type that does not support inheritance. Actors in Swift are isolated objects that provide safe access to state in a multithreaded environment.

If you need to extend the functionality of an actor, composition or protocols are usually used instead of inheritance. This is because actors are implemented as isolated entities, and inheritance would break the isolation model.
