How to find the translation from a CGAffineTransform

Paul Hudson       @twostraws

You can pull out the translation from a CGAffineTransform by using the function below. Feed it a transform and it will return you a CGPoint:

func translation(from transform: CGAffineTransform) -> CGPoint {
    return CGPoint(x: transform.tx, y: transform.ty)
}

Available from iOS 2.0
