Answer 2

Swift 4.2

UIBarButtonItem.appearance().setTitleTextAttributes([.foregroundColor: UIColor.clear], for: .normal)

Answer 3

Updated Answer For Swift 4.2

Working with UIAppearance is a cleaner way of solving the problem but it would cause all the UIBarButtonItem to have a clear text. An improved version of the solution could be to check if the UIBarButtonItem is contained in a UINavigationBar.

    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self]).setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.clear], for: .normal)

Answer 4

Put the below code in any of the UIViewcontroller extension it will hide all the UIViewcontroller back text

open override func awakeFromNib() {
        navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
    }

Answer 5

I have found a simple solution:-

at PersingtingViewController's viewWillDisappear method jsut put

self.title = ""

and set title for PersingtingViewController's on viewWillAppear method. And repeat this for all viewControllers of navigationStack except for last one.

Using the line of code in AppDelegate file into didFinishLaunchingWithOptions

    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self]).setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.clear], for: .normal)

    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self]).setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.clear], for: .highlighted)
