fatal error: unexpectedly found nil while unwrapping an Optional value swift error

I am writing a simple program that shows and takes away images and I keep getting the error

fatal error: unexpectedly found nil while unwrapping an Optional value

Here is my code:

@IBAction func BeginButton(sender: AnyObject) {
    self.Retry.hidden = false
    self.Begin.hidden = true
    self.Logo.hidden = true
    self.GameOver.hidden = false
    self.ScoreBoard.hidden = false
}

@IBAction func RetryButton(sender: AnyObject) {
    self.Begin.hidden = false
    self.Retry.hidden = true
    self.Logo.hidden = false
    self.GameOver.hidden = true
    self.ScoreBoard.hidden = true
}

Please help me!

You need to connect your IBOutlets (self.Retry, self.Begin, ...) with the corresponding views in Interface Builder. Right now, one or more of them are nil.

Here's a detailed explanation from Apple: https://developer.apple.com/library/ios/referencelibrary/GettingStarted/DevelopiOSAppsSwift/Lesson3.html
