yea, ui design in xcode is very speical, Storyboard and Segues ... i couldn't sleep for about an week cause of that.
Instead of an motivation count I could give you a tipp:
F**k off having all UI's in one Storyboard using Segues (the way like apple want you to do it)
and apply it to UI Controller per code using your own structure. You can even apply UI's from different storyboards on your UI Controller.
(greetings from a short trip to the apple world,
hope you'll have more luck and endurance)
