How do I call a textfield from within an UIAlertController?

So, I am making an app where when the "Start" button is pressed, an Alert via UIAlertController pops up and there are two textfields asking for the players' names, where I will move the player names to the game's screen (it's a Tic-Tac-Toe app) via

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)

So my question at the moment is how to get the values that the user inputs into the TextFieldWithConfigurationHandler to my GameScreen. My code for the UIAlertController is as follows:

@IBAction func startButton(sender: AnyObject)
    {
        var playerNameEntry = UIAlertController(title: "Player names", message: nil, preferredStyle: .Alert)

        playerNameEntry.addTextFieldWithConfigurationHandler({textfield in textfield.placeholder = "Player 1"})

        playerNameEntry.addTextFieldWithConfigurationHandler({textfield in textfield.placeholder = "Player 2"})

        var continueButton = UIAlertAction(title: "Continue", style: .Default, { action in

            self.performSegueWithIdentifier("gameSegue", sender: nil)

        })

        playerNameEntry.addAction(continueButton)

        var cancelButton = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)

        playerNameEntry.addAction(cancelButton)

        self.presentViewController(playerNameEntry, animated: true, completion: nil)

    }

thanks for taking to time to read this and if you answer, thanks tenfold

In your continueButton handler, you have access to the alert controller as playerNameEntry. Therefore you can access its textFields array:

https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIAlertController_class/#//apple_ref/occ/instp/UIAlertController/textFields

Therefore you can access the text of each of those text fields.

    var continueButton = UIAlertAction(title: "Continue", style: .Default, { action in
        // code goes here
        let tfs = playerNameEntry.textFields as [UITextField]
        // ...do stuff with the `text` of each text field...
        self.performSegueWithIdentifier("gameSegue", sender: nil)
    })
