You can also type 'label' in the filter tab at the bottom of the object library.

Remember to wrap it by adding the exclamation mark

2. The View tag will show.

You can set the number of lines that a label can have.

Animate labels so that they swish

UIView.animate(withDuration: 0.5) { 

            self.lab1.center.x += self.view.bounds.width

        }

Double click the second parameter to get to the code

OR:

UIView.animate(withDuration: duration, delay: delay, options: .curveEaseOut, animations: {

            object.center.x += self.view.bounds.width

        }) { (true) in

            

        }
