Nil unwrapping (Error)

Hello!

Does anyone know how I can debug the following error: "Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value"?

And maybe what "nil" even means?

The error displays in the following code (line 18):

Code Block  func updateUI() {
        var letters = [String]()
        for letter in currentGame.formattedWord {
            letters.append(String(letter))
        }
        let wordWithSpacing = letters.joined(separator: " " )
        
        correctWordLabel.text = currentGame.formattedWord
        scoreLabel.text = "Wins: \(totalWins), Losses: \(totalLosses)"
        treeImageView.image = UIImage(named: "Tree \(currentGame.incorrectMovesRemaining)")
    }


Thank you so much!
