xcode - How to connect a button to a new view controller iOS Swift? -


i'm pretty new swift , trying connect button view controller. on other apps have made swift have been able control-drag button view controller, display "show" option click. when run , click button show desired view controller.

on app working on, trying add settings page accessed clicking button. when tried control-click , drag button second view control, displayed 3 options: push, modal, , custom. selected push, , when ran app , pressed button showed sinabrt error. how can connect button second view controller pressing it?

you see "show" option if working on project targeting ios 8 , later, since new feature determine proper way show new view controller. opt "push" if in navigation controller , "modal" if in regular controller context.

here might working project deploy target ios 7 or below. can choose use "modal" here present view controller bottom of screen , implement exit button. or can embed current view controller navigation controller use "push" make new view controller pushed right hand left, button navigating automatically.
