Remember, outlet is for variables and action is for functions.…The data type is going to be UILabel.…And then we'll call it label.…And again, there's an asterisk because it's not a number value.…Now we're going to declare the function that…we want to connect to the button press.…We do that outside of the curly braces, so hyphen, and then in parentheses, IBAction.…We'll call this didScore, with a capital s, and put…a semicolon at the end of this line of code.…
