Error! highlighted in green

fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)

My code:

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var funFactLabel: UILabel!

let factBook = FactBook()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    funFactLabel.text = factBook.factsArray[0]

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func showFunFact() {
    funFactLabel.text = factBook.factsArray[1]
}

}
