Not sure I'm sold on () -> Void

kconner commented 8 years ago

I endorse () -> Void:

in swift 3, function types require tuple parentheses even around a single argument (Int -> Int should be (Int) -> Int), so () is more natural than Void on the left.
apple does it this way: class func animate(withDuration duration: TimeInterval, animations: @escaping () -> Void)
