You will need to share your project with us to figure out where in your code the application is crashing.

You have a value someone, an optional, which hasn't been instantiated and you are they trying to unwrap it causing the crash.

I managed to solve it on my own. The "@IBOutlet var funFactLabel: UILabel!" was misplaced after the "let factBook = FactBook()" Placing it above the assigned constant fixed the issue. Thanks anyway.

For future reference, if you have a question, it is better to post with your code so other students can help you and give accurate answers
