Segue won't execute Swift

问题

I have a segue running form a Collection View (wrapped in a view controller) in to a another view controller, how ever the function never gets called:

  func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
  println(segue.identifier)
  println(sender)
  println("SEGUE SELECTED:  \(segue.identifier)")

  if(segue.identifier == "segueToDetailView") {
    let cell = sender as CollectionViewCell;
  }
}

Have placed a breakpoint at start of function but never reached.

Any input appreciated.

I will suggest not to create segue(s) from cell or any object(like button). Create segue from one ViewController to OtherViewController with unique identifier. And then call the performSegueWithIdentifier yourself using the identifier.
