Updated swift 4.0 version:

    let rotation: CABasicAnimation = CABasicAnimation(keyPath: "transform.rotation.z")
    rotation.toValue = Double.pi * 2
    rotation.duration = 0.25 // or however long you want ...
    rotation.isCumulative = true
    rotation.repeatCount = Float.greatestFiniteMagnitude
    yourView.layer.add(rotation, forKey: "rotationAnimation")
