Promisekit: Help me - Chaining recursive without knowing how many loops I'll have.

[igordeoliveirasa]

I would like to make async query while last query returns nil. How to chain something like that? I can't create an array before, since I don't know how many chaining loops I will have.

func bar() -> Promise<T?> {
    //…
}

func baz() -> Promise<T> {
    return bar().then {
        if let done = value {
            return Promise(value: done)
        } else {
            return baz()
        }
    }
}

baz().then { value in
    // all done
}
