Create a class variable counter and initialize it to 0.
Change fact = facts[randomNumber]; to fact = facts[counter].
Increment counter each time you click the fact button: counter += 1
Then add this conditional, just after you increment counter, to make sure you don't increment too far: if counter > facts.count { counter = 0; } This resets counter to 0, to start over.
