UIView shake animation

i\'m trying to make a UIView shake when a button is pressed.

I am adapting the code I found on http://www.cimgf.com/2008/02/27/core-animation-tutorial-window-shake-e

Answer 1

@imike answer in Swift 4.2

extension UIView {
func shake() {
    let animation = CAKeyframeAnimation(keyPath: "transform.translation.x")
    animation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear)
    animation.duration = 0.6
    animation.values = [-20, 20, -20, 20, -10, 10, -5, 5, 0]
    self.layer.add(animation, forKey: "shake")
}}
