Xcode 6: fatal error: unexpectedly found nil while unwrapping an Optional value

I keep getting this error when I run my program in Xcode:

fatal error: unexpectedly found nil while unwrapping an Optional value

Here's my code:

@IBOutlet var textFielD: UITextField!

@IBOutlet var message: UILabel!

@IBAction func guessButton(sender: AnyObject) {

    var numberOfFingers = arc4random() % 6

    println(numberOfFingers)

    var numberOfFingersString = String(numberOfFingers)


    if (numberOfFingersString == textFielD.text!) {

        message.text = "You got it right!"

    } else {

        message.text = "Nope! I was holding up \(numberOfFingers) fingers. Try again!"

    }

I am working in Xcode 6.1.1 (the most recent version) on an iMac running Yosemite.

Thank you for the help.

Either textFielD (note 'spelling' error) or message is not linked in Interface Builder. Check that all outlets are bound. IBOutlets are always declared as implicitly unwrapped optionals - you need to bind them in Interface Builder or in viewDidLoad (or a similarly early method).
