Swift, actor: Actor-isolated 属性 'scanning' cannot be mutated from a non-isolated context

Question

我有一个演员：

actor StatesActor {

    var job1sActive:Bool = false
    ...

}

我有一个使用该演员的对象：

class MyObj {
    
    let myStates = StatesActor()
    
    func job1() async {
    
        myStates.job1IsActive = true

    }
}

行：

myStates.job1IsActive = true

出现此错误：

Actor-isolated property 'job1IsActive' can not be mutated from a non-isolated context

如何使用 actor store/read 正确地声明信息，以便 MyObj 可以使用它来读取和设置状态？

Answer 1

How can I use an actor to store/read state information correctly so the MyObj can use it to read and set state?

您不能从 actor 外部改变 actor 的实例变量。这就是演员的全部意义！

相反，给角色一个方法来设置它的own实例变量。然后您将能够调用该方法（使用 await）。
