Here is the swift code for it ;)

let pulseAnimation:CABasicAnimation = CABasicAnimation(keyPath: "transform.scale")
pulseAnimation.duration = 1.0
pulseAnimation.toValue = NSNumber(value: 1.0)
pulseAnimation.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeInEaseOut)
pulseAnimation.autoreverses = true
pulseAnimation.repeatCount = .greatestFiniteMagnitude
self.view.layer.add(pulseAnimation, forKey: nil)
