How to shake NSView in macOS

Issue #233

Animation on macOS using CAAnimation

Shake

let midX = box.layer?.position.x ?? 0
let midY = box.layer?.position.y ?? 0

let animation = CABasicAnimation(keyPath: "position")
animation.duration = 0.06
animation.repeatCount = 4
animation.autoreverses = true
animation.fromValue = CGPoint(x: midX - 10, y: midY)
animation.toValue = CGPoint(x: midX + 10, y: midY)
box.layer?.add(animation, forKey: "position")

Animation on macOS using NSAnimationContext

Wiggle

NSAnimationContext.runAnimationGroup({ context in
    let animation = CAKeyframeAnimation(keyPath: "transform")
    animation.beginTime = CACurrentMediaTime() + 5.0
    animation.duration = 0.1
    animation.autoreverses = true
    let wobbleAngle: CGFloat = 0.08
    animation.values = [
        NSValue(caTransform3D: CATransform3DMakeRotation(wobbleAngle, 0.0, 0.0, 1.0)),
        NSValue(caTransform3D: CATransform3DMakeRotation(-wobbleAngle, 0.0, 0.0, 1.0))
    ]
    view.layer?.add(animation, forKey: "transform")
}, completionHandler: {
    self.makeAnimation(view: view)
})

Animation on iOS using UIView animation block

extension UIView {
    func shake() {
        self.transform = CGAffineTransform(translationX: 16, y: 0)
        UIView.animate(withDuration: 0.4, delay: 0, usingSpringWithDamping: 0.2, initialSpringVelocity: 1, options: .curveEaseInOut, animations: {
            self.transform = CGAffineTransform.identity
        }, completion: nil)
    }
}
