I have an Unwind segue that does work programmatically but works tied to a button

I have a app project I am working on. I created an unwind segue in my main view as

   @IBAction func unwindToHomeScreen(segue:UIStoryboardSegue) {
}

It works from another view from the cancel button

however in the same view when I call the segue

self.performSegueWithIdentifier("unwindToHomeScreen", sender: self)

The app crashes with

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<TravelSave.AddVacationTableViewController: 0x7907f380>) has no segue with identifier 'unwindToHomeScreen''

Any suggestions?
