Yes, an actor can be sendable in Swift. In the context of Swift 6, sendability is an important concept for ensuring data race safety when dealing with concurrency. Actors in Swift are reference types that can encapsulate shared mutable state and automatically protect their state by serializing accesses, which makes them inherently suitable for concurrent programming.
In the session "A Swift Tour: Explore Swift’s features and design," it is explained that actors are similar to classes but provide automatic protection against data races by allowing only a single task to execute at a time on an actor. This makes actors a convenient feature for ensuring that values shared between concurrency domains are sendable, as they protect their state from concurrent accesses (A Swift Tour: Explore Swift’s features and design).
Additionally, in the session "Migrate your app to Swift 6," it is discussed that for a type to be sendable, it must not contain mutable state that can be accessed concurrently. If a type is public, Swift requires explicit conformance to the Sendable
protocol to guarantee to clients that the type is safe to be used across concurrency domains (Migrate your app to Swift 6).
