Maybe my Google skills are failing me, but I can't find any documentation or tutorials on how to create a popover segue in Storyboard. I've found several that create a popover programmatically, but none for Storyboard. I tried creating a ViewController in the Storyboard, then a Popover segue to it. Link the segue's anchor to a view in the source scene (is that correct?). But when I trigger the segue, prepareForSegue: gets called, then... nothing.
