如何制作`nsviewController` a@mainactor`并实现nsmenuitemvalidation“ a@mainactor”
我有一个自定义nsviewController实现nsmenuitemvalidation协议的子类。这很好，直到我将视图控制器标记为@mainactor。
我认为苹果将所有视图控制器都标记为主要演员已经隔离了，但也许只能在iOS上这样做。但是我认为标记我的子类是安全的。
一旦添加@MainActor行，我就会获得警告>实例方法“ validatemenuitem”隔离到全局actor'mainactor'无法满足协议'nsmenuitemvalidation'：
@MainActor
final class MyViewController: NSViewController, NSMenuItemValidation {
func validateMenuItem(_ menuItem: NSMenuItem) -> Bool {
}
}
IS IS 的相应要求。标记自定义nsviewController子类是@MainActor是不是可以的吗？还是我应该如何处理此警告？
我想标记我的视图控制器，因为它需要与（明确）隔离到主要演员的其他类别，我想避免完全不是必需的异步边界，知道视图控制器将始终运行主线程。
I've a custom NSViewController subclass that implements the NSMenuItemValidation protocol. That works just fine, until I mark the view controller as @MainActor.
I believed Apple marked all view controllers as main actor isolated already, but maybe it does so only on iOS. But I thought it would be safe to mark my subclass as such.
Once I add the @MainActor line, I get the warning Instance method 'validateMenuItem' isolated to global actor 'MainActor' can not satisfy corresponding requirement from protocol 'NSMenuItemValidation':
@MainActor
final class MyViewController: NSViewController, NSMenuItemValidation {
func validateMenuItem(_ menuItem: NSMenuItem) -> Bool {
}
}
Is it not okay to mark a custom NSViewController subclass as @MainActor? Or how should I deal with this warning?
I want to mark my view controller, because it needs to co-operate with other classes that are (explicitly) isolated to the main actor and I want to avoid various async boundaries that are totally not necessary, knowing the view controller will always run on the main thread.

您必须标记带有非分离的函数。我假设这是因为NSMENUITEMVALIDATION协议不限于主队列。
非分离的func dastemenuitem（_ benuitem：nsmenuitem） - ＆gt; bool {}You must mark the function w/ nonisolated. I'm assuming this is because the NSMenuItemValidation protocol is not restricted to the main queue.
nonisolated func validateMenuItem(_ menuItem: NSMenuItem) -> Bool { }
