iOS 8 (Xcode 6.1.1) - Navigation bar not working as in storyboard -

i'm following youtube tutorial swift ios tutorial - core data - add update delete part1 (xcode 6 beta) done in different xcode version , encountering navigation issues wasn't apparent in tutorial. suppose changes in latest xcode hope 1 might able address here.

i have 1 tableviewcontroller embeded in navigationcontroller (initial view) , tableviewcontroller, made push segue + bar item viewcontroller. in simulation mode, + button displays edit , clicking doesn't go viewcontroller should push to.

this how it's done in storyboard.

and, simulation screen button wrong , clicking doesn't go next screen.

**updated

check segue connection, if have given cell, if there record navigate next view. other wise give segue connection edit button next view testing purpose.
