Is it possible to expect thread safety issues when creating a subclass of Actor?

In Swift, Actor is designed to ensure thread safety when working with state inside an actor. It serializes access to its internal data, so when used correctly, it prevents data races.

However, if unsafe operations are used inside an actor, such as accessing shared resources outside the actor without synchronization, or using unsafe pointers, then thread safety issues can still occur.

Therefore, the Actor itself provides protection against data races, but improper use or bypassing actor mechanisms can lead to thread safety problems.
