after trying many things and searching for all the related questions and not being able to fix the issue.
this is the current situation in the storyboard:
the top bar of the home tableviewcontroller does not show up even though in the login and signup view controllers it does. the segues from those view controllers are triggered programatically in the actions triggered by button clicks. even when setting the top bar to be opaque/translucent and not inferred it still wouldn't show up.
---- update -----
tried adding navigation controller: added navigation controller
it doesn't even perform the segue now... because the initialisation in the prepare for segue is preparing a different destination view controller. tried to make a custom navigation controller class but that made problems as well.
please help!
