[swift-users] Is 'self' retained instead of member-function?

[Daniel Tartaglia]

In the code below, I’m confused as to wether ‘self’ is owned, unowned or retained inside the ‘bar()’ function. I was assuming that it would always be retained, but I am wondering if that’s correct… Especially the ‘unownedThunk’ example… I don’t recall anything in the Swift book explicitly answering this question.


class Foo {

    init() {
        ownedThunk = {
            self.bar()
        }
        unownedThunk = { [unowned self] in
            self.bar()
        }
        weakThunk = { [weak self] in
            self?.bar()
        }
    }

    func bar() {
        // is 'self' owned/unowned/weak? here?
    }

    private var ownedThunk: () -> Void = { }
    private var unownedThunk: () -> Void = { }
    private var weakThunk: () -> Void = { }

}
