ios - Button Does Not Segue on First Click -


i have view controller segues multiple other view controllers. 1 of segues clicking on collection view cell , add button, both work perfectly.

however added uibarbutton item segues view controller , have created segue in main.storyboard instead of programmatically, issue when run app on phone, button not respond, if click on collection view cell segue works fine , when go using navigation bar button , press on uibarbutton segues when pressed fine.
