This can also occur if you've got (say) a UIButton hooked up to an IBAction to present a ViewController, and also create a segue in the Storyboard from the button to the target ViewController.
Had this happen when I forgot to delete the IBAction connection from a UIButton when I shifted some interactions around.
Deleting either the IBAction connection or the segue will resolve it.
