How would I generate the next value in an array instead of a random one for my fun facts app?

when I click my fact button I would like to see the next fact in my array instead of a random one.

terrence, here are the basic steps: 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.
