Shake animation with swift

UIView+Animations.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")
    }
}

works like a charm (tested with textFields)

Updated for swift 4:

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 {
            ( degrees: Double) -> Double in
            let radians: Double = (.pi * degrees) / 180.0
            return radians
        }
        
        let shakeGroup: CAAnimationGroup = CAAnimationGroup()
        shakeGroup.animations = [translation, rotation]
        shakeGroup.duration = duration
        self.layer.add(shakeGroup, forKey: "shakeIt")
    }
}

Very nice!

For folks using this for MacOS App

extension NSView {
    func shake(duration: CFTimeInterval) {
        let translation = CAKeyframeAnimation(keyPath: "transform.translation.x");
        translation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.linear)
        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 {
            (degrees: Double) -> Double in
            let radians: Double = (.pi * degrees) / 180.0
            return radians
        }

        let shakeGroup: CAAnimationGroup = CAAnimationGroup()
        shakeGroup.animations = [translation, rotation]
        shakeGroup.duration = duration
        self.layer?.add(shakeGroup, forKey: "shakeIt")
    }
}

Awesome Guys!
Can we please have a completion call back as well

Thanks guys, great work 👍

Updated for Swift 5.0

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 { (.pi * $0) / 180.0 }
        
        let shakeGroup = CAAnimationGroup()
        shakeGroup.animations = [translation, rotation]
        shakeGroup.duration = 1.0
        layer.add(shakeGroup, forKey: "shakeIt")
    }
}

@shawnwall, @aayusharyan and @rmnblm, many thanks for your updates

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

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")
    }
}

myTextField..shake(duration: 1.0)

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")
    }
}

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