NSTextField And AutoLayout: Autogrow height -> Programmatically

Question

If I create a label in interface builder and set a string through code that does not fit its current size, the label will grow vertically to fit its size, great!. Besides th

I think a better way to do this, is to override NSTextField, and update the intrinsicContentSize.

public class DynamicTextField: NSTextField {
   public override var intrinsicContentSize: NSSize {
      if cell!.wraps {
         let fictionalBounds = NSRect(x: bounds.minX, y: bounds.minY, width: bounds.width, height: CGFloat.greatestFiniteMagnitude)
         return cell!.cellSize(forBounds: fictionalBounds)
      } else {
         return super.intrinsicContentSize
      }
   }

   public override func textDidChange(_ notification: Notification) {
      super.textDidChange(notification)

      if cell!.wraps {
         validateEditing()
         invalidateIntrinsicContentSize()
      }
   }
}

Afterwards the constraints works as expected. Note that it only works when you set the Layout to Wraps in Interface Builder or code.
