SOLVED: Hacking with macOS, Project 2

Forums > Books

Hi there,

I'm a total newbie to macOS programming who gets totally distracted by a problem I can not solve: When I enter a 4 digit number into the text field and press the "Guess" button only "Table View Cell" is displayed twice in a row. What did I do wrong? Probably something quite obvious but I don't recognize it.

Thanks in advance and for your patience!
