Question

I have an Xcode project that doesn t use self. inside of a closure where it s needed.

class Example {
    func bar() {   
        DispatchQueue.main.async { [weak self] in
            guard let self = self else {
                return
            }

            print(foo) // should be print(self.foo), but not getting an error here
        }
    }
    
    var foo: String {
        "foo"
    }
}

尽管如此,该建筑仍在当地成功。我预计以下错误也会在当地出现:

提及关闭时的财产oo,需要明确使用自我,以明确捕捉 se
