uiviewcontroller - Swift popToRoot not working -

this highlighted line should poptoroot proceed, after successful registration should redirect root view controller. reason it's not working me, literally nothing happens, not error.

i tried

self.navigationcontroller?.poptorootviewcontrolleranimated(true) 

you don't appear using navigation controller @ all, i'd wager self.navigationcontroller nil.

you use unwind segue. in root view controller, add method so:

@ibaction func unwindtoroot(segue: uistoryboardsegue) {     print("successfully unwound") } 

then in scoreboard scene want unwind, can control-drag button "exit outlet":

when let go, can pick unwind action:

this achieves "pop root" sort of functionality, not contingent upon using navigation controller.

---

if want perform unwind programmatically, rather doing segue button exit outlet, view controller icon exit outlet:

then, select segue in document outline , give segue unique storyboard id:

then can programmatically perform segue, using same identifier string:

performseguewithidentifier("unwindtoroot", sender: self)
