*edit - using storyboard bunch of segues (i'm new programming , self taught, idk if right way or not)... here pic of storyboard

ok, @ storyboard, think see problem. if storyboard looks spilled spaghetti on it, it's not designed correctly. specifically, looks you're going "backwards" (to controllers you've been to) using segues -- that's not good. segues instantiate new controllers! so, if go around in circle few times, you're adding more , more controllers project. go backwards using segues, need use unwind segue -- it's 1 exception rule segues instantiate new controllers. other ways go backwards, without segues, popping navigation controllers, , dismissing modal controllers.

i can't diagnose immediate problem without lot more information, redesigning storyboard using unwind segues fix problem.
