Actor in Swift

Swift introduces Actors in version 5.5 and this is a big change in concurrency at WWDC. The actors main used to manage shared state often leads to Data races and Race conditions problems in a concurrent system. In-sort two pieces of code can’t access an actor’s data at the same time.Actors are like other Swift types as they can also have initializers, methods, properties, and subscripts, while you can also use them with protocols and generics. Furthermore, unlike structs, an actor requires defining initializers when your defined properties require so manually

Some key concepts about actors:

• The actor is a Reference Type
• To access actors’ property we have to put await keyword before calling.
• The actor does not support inheritance but we can implement the protocol.
• An actor automatically serializes all access to its properties and methods, which ensures that only one caller can directly interact with the actor at any given time.

Note: The above code makes you lose the whole state of your app.
