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

I get this console error in my code, fatal error: unexpectedly found nil while unwrapping an Optional value (lldb). There is also a error in the document saying "EXC_BAD_INSTRUCTION", can anyone help me?

import UIKit

class ViewController: UIViewController {


    @IBOutlet weak var funFactLabel: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()
        funFactLabel.text = "An interesting fact!" //This is where the error occurred
    }

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

    @IBAction func showFunFact() {
        print("You pressed me!")
    }


}

Hello :

Try reconnecting the IBoutlet "funFactLabel". Perhaps at some point it got disconnected.

Good luck
