Need help fixing error: "fatal error: unexpectedly found nil while unwrapping an Optional value"

I'm not sure why I am receiving this error on my funFactButton.tintColor = randomColor line.

Found out the problem. Somehow I unlinked my "funFactButton" from the ViewController. Once linked back to the Controller, nil was no longer the out come of unwrapping the Optional value, "funFactButton".
