Swift’s actors are conceptually like classes that are safe to use in concurrent environments. This safety is made possible because Swift automatically ensures no two pieces of cod...

Creating and using an actor in Swift takes two steps: create the type using actor rather than class or struct, then use await when accessing its ...

Swift's actors run on their own executor most of the time, so they manage how and where their work is done. However, during the actor's initialization its executor isn't ready to t...

Any properties and methods that belong to an actor are isolated to that actor, but you can make external functions isolated to an actor if you want. This allows the funct...

All methods and mutable properties inside an actor are isolated to that actor by default, which means they cannot be accessed directly from code that’s external to the actor. Acce...

@MainActor is a global actor that uses the main queue for executing its work. In practice, this means methods or types marked with @MainActor can (for the most part)...

One common confusion with actors comes in deciding exactly where code runs, because just adding @MainActor and hoping for the best is rarely good enough.与 Actor 的一个常...

Apple explicitly annotates many of its types as being @MainActor, including most UIKit types such as UIView and UIButton. However, for a while the Swift team da...

When a thread pauses work on one actor to start work on another actor instead, we call it actor hopping, and it will happen any time one actor calls another.当线程暂停对一个 a...

Actor-isolated functions are reentrant, which means it's possible for one piece of work to begin before a previous piece of work completes. This opens the possibility of subtle bug...
