Figuring out the size of the textBox in a CATextLayer

I wrote this code, works well; but I need to figure out the size of the text in the CATextLayer to finish it? The idea I use from a tap gesture to get the x/y, enter the text and have it figure out the CGSize needed to draw it in the CATextLayer object/view. ``` overload func ViewDidLoad() let tap = UITapGestureRecognizer(target: self, action: #selector(handleTap)) container.addGestureRecognizer(tap) } func handleTap(gesture: UITapGestureRecognizer) { let location = gesture.location(in: gesture.view) startX = location.x startY = location.y drawText(onLayer: view.layer, fromPoint: CGPoint(x: startX, y: startY), toPoint: CGPoint(x:location.x, y:location.y)) } func drawText(onLayer layer: CALayer, fromPoint start: CGPoint, toPoint end:CGPoint) { let myTextLayer = CATextLayer() myTextLayer.string = "Google" myTextLayer.backgroundColor = UIColor.black.cgColor myTextLayer.foregroundColor = UIColor.white.cgColor //myTextLayer.frame = view.bounds let myBounds = CGRect(origin: start, size: CGSize(width: 128, height: 32)) myTextLayer.frame = myBounds layer.addSublayer(myTextLayer) } ```
