rightBarButtonItem disappears on pop in iOS-9 and iOS-10

Question

I already read multiple posts regarding this, but couldn't get it working.

Posts I already read:

I have a ViewController-A embedded in a UINavigationController. The navigation bar of the controller contains a rightBarButtonItem. Code for adding rightBarButtonItem:

let searchButton = UIBarButtonItem(image: UIImage(named: "HomeSearch"), style: .plain, target: self, action: #selector(navigateToSearchScreen))
self.navigationItem.rightBarButtonItem = searchButton

When another ViewController-B is pushed in the navigation stack and popped back, the rightBarButtonItem disappears from the navigation bar.

@AbdelahadDarwish I've already shared the code that I have used. — PGDev, May 14 '18 at 08:48
Navigation process you just add button to navigationbar, where is navigation process , back action ...etc — Abdelahad Darwish, May 14 '18 at 08:49
viewDidDisappear contains any kind of code ? in either of the classes , or anywhere is rightbarbutton assigned nil — Nilomi Shah, May 14 '18 at 09:01
Actually, I added the code to add `rightBarButton` in `viewDidAppear`. But it is still not smooth. I checked in the UI debugger that when I pop the controller, the button is still there, only the hierarchy of `UINavigationBar` is changed. I don't understand what could be the reason for that. — PGDev, May 18 '18 at 09:20

I think in nextViewcontroller you hide the navigation right bar so When you pop then nav button will not display So You have to add right bar button in viewWillAppear:

override func viewWillAppear(_ animated: Bool) {
        let searchButton = UIBarButtonItem(image: UIImage(named: "HomeSearch"), style: .plain, target: self, action: #selector(navigateToSearchScreen))
        self.navigationItem.rightBarButtonItem = searchButton
    }

Navigation bar is visible. Just the rightBarButton disappeared. – PGDev May 14 '18 at 08:24
Yes, Only right bar button hide. Have you tried this in viewWillAppear? – Jogendar Choudhary May 14 '18 at 08:29
