Shake animation with swift
extension UIView {
func shake(duration: CFTimeInterval) {
let translation = CAKeyframeAnimation(keyPath: "transform.translation.x");
translation.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionLinear)
translation.values = [-5, 5, -5, 5, -3, 3, -2, 2, 0]
let rotation = CAKeyframeAnimation(keyPath: "transform.rotation.z")
rotation.values = [-5, 5, -5, 5, -3, 3, -2, 2, 0].map {
(let degrees: Double) -> Double in
let radians: Double = (M_PI * degrees) / 180.0
return radians
}
let shakeGroup: CAAnimationGroup = CAAnimationGroup()
shakeGroup.animations = [translation, rotation]
shakeGroup.duration = duration
self.layer.addAnimation(shakeGroup, forKey: "shakeIt")
}
}

updated for swift 5.1

extension UIView {
    func shake(duration: CFTimeInterval) {
        let shakeValues = [-5, 5, -5, 5, -3, 3, -2, 2, 0]

        let translation = CAKeyframeAnimation(keyPath: "transform.translation.x");
        translation.timingFunction = CAMediaTimingFunction(name: .linear)
        translation.values = shakeValues
        
        let rotation = CAKeyframeAnimation(keyPath: "transform.rotation.z")
        rotation.values = shakeValues.map { (Int(Double.pi) * $0) / 180 }
        
        let shakeGroup = CAAnimationGroup()
        shakeGroup.animations = [translation, rotation]
        shakeGroup.duration = 1.0
        layer.add(shakeGroup, forKey: "shakeIt")
    }
}

Is there sample code that show us how to use it with Images or TextFields etc ?

myTextField..shake(duration: 1.0)

        shakeGroup.animations = [translation, rotation]
        shakeGroup.duration = 1.0
        layer.add(shakeGroup, forKey: "shakeIt")
    }
}

Many thanks for the update. You maybe forgot to use the animation duration parameter:
shakeGroup.duration = duration
insteed of
shakeGroup.duration = 1.0
