IOS segue id is an empty string to prepare for segue

Question

I have an identifier with an identifier.

When I click the button in the shouldPerformSegueWithIdentifier function, I get an empty identifier

What can cause such a problem? What did I create wrong?

Here is my code:

override func shouldPerformSegueWithIdentifier(identifier: String, sender: AnyObject!) -> Bool {

    if identifier == segueIdentifier {
        return false
    }
    else if identifier == registrationSegueidentifier {
        if checkEULA() == true {
            return true
        }
        else {
            showEULAToUser()
            return false
        }
    }

    return true
}

Perhaps you could localize your storyboard, so the results are that you now have two storyboards. So, you added the identifier to the base storyboard, and you may have forgotten to add this identifier to another storyboard. Do research in this direction.
