override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "BasicPhrasesVC2BasicDisplayVC" {
            if let nextVC = segue.destinationViewController as? NextViewController {
                nextVC.selectedBasicPhrase = sender
            }
        }
    }

Answer 2

Check segue name than take destinationViewController and send you're data to it.

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "BasicPhrasesVC2BasicDisplayVC") {
        let viewController:ViewController = segue!.destinationViewController as ViewController
        viewController.selectedBasicPhrase = "Test phrase"
    }
}

Answer 3

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "<segue name>") {
        // pass the data
    }
}
