2. Set the textField’s delegate to self. Place paste this code on the line below the textField’s constraints (under line 21).

3. Extend the ViewController class with the following code. The textFieldShouldReturn function will be called whenever the return button is clicked.

4. Now finally combine all of the code so that it looks like this

Congratulations! You now know how to programmatically make the keyboard disappear when the return button is clicked!
