On toggle NavigationController's navigation bar(show/hide) the problems with back button and its tint color

[MuhammadNayabButt]

On previous screens I have hidden the navigation controller. When I come to the required viewcontroller I unhide/show the view controller using this command

self.navigationController?.setNavigationBarHidden(false, animated: true)

strangely after unhiding the navigation controller not even backbutton hides properly neither its tint changes.
like following two lines of code does not have any effect. I get the back button in only blue colour

navigationItem.backButton.isHidden = true
navigationItem.backButton.tintColor = UIColor.black

it seems there is a problem with native navigationController although I am using only material navigation controller.

I have attached a sample project as well which can help you debug the issue
