I have a View hierarchy
there is just one navigation controller and its rootViewController.
I want to add a left bar button item at the view which is circled.
the View I want to add barButton:
I tried
self.navigationController?.navigationItem.leftBarButtonItem = editButtonItem
in viewDidLoad() and viewWillAppear() but none of them worked out.
I also tried adding UINavigationItem in storyBoard and then adding barButtonItem. this didn't work too.
EDIT

my output after trying answers:
any help would be appreciated.
