Blocks on Swift (animateWithDuration:animations:completion:)

Question

I\'m having trouble making the blocks work on Swift. Here\'s an example that worked (without completion block):

UIView.animateWithDuration(0.07) {
    self.so         


        

Answer 1

SWIFT 3.x + 4.x

I'd like to make an update and simplify the things.

Example below is implemented in any view it is hiding slowly and when it is completely transparent; removes it self from parent view

ok variable will always returns true with animation termination.

    alpha = 1
    UIView.animate(withDuration: 0.5, animations: {
        self.alpha = 0
    }) { (ok) in
        print("Ended \(ok)")
        self.removeFromSuperview()
    }
