Prepare for segue error in lldb

I'm calling it like this

    override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {

    if (segue.identifier == "hat") {
        let itemVC: ItemViewController = sender.destinationViewController as ItemViewController
        itemVC.myDelegate = self
        itemVC.nameArray = self.nameArray
    }
}

but the lldb freezes up once I call to go to the next view controller. Any idea whats going on?

I believe you want:

segue.destinationViewController

instead of:

sender.destinationViewController
