I’m currently building a simple app to learn the protocol – delegate functionality. However my code doesn’t work, even after I edited the way I did in my first practice app where it worked. In the FirstViewController there is a UILabel and a UIButton. When the user taps on the UIButton, a segue brings them to the SecondViewController where they should enter their name into a UITextField. After that, they can press the UIButton in the SecondViewController and the entered Name should be displayed in the UILabel in the FirstViewController.
