Navigation controller title not showing up?

So when I have my OptionsViewController as the rootViewController in the AppDelegate didFinishLaunchingWithOptions...

let rootVC = OptionsViewController()
        let navigationController = UINavigationController(rootViewController: rootVC)
        navigationController.navigationBar.barTintColor = .white
        navigationController.navigationBar.isTranslucent = false
        navigationController.navigationBar.tintColor = .black
        self.window = UIWindow(frame: UIScreen.main.bounds)
        self.window!.rootViewController = navigationController
        self.window?.makeKeyAndVisible()

...setting the title of the OptionViewController works if I do this in viewDidLoad():

    title = "Route Options"

enter image description here

But when I push OptionsViewController onto the navigation stack the title doesn't show up.

I.e. if I start w/ a different view as the rootViewController in AppDelegate:

 let rootVC = HomeViewController()
    let navigationController = UINavigationController(rootViewController: rootVC)
    navigationController.navigationBar.barTintColor = .white
    navigationController.navigationBar.isTranslucent = false
    navigationController.navigationBar.tintColor = .black
    self.window = UIWindow(frame: UIScreen.main.bounds)
    self.window!.rootViewController = navigationController
    self.window?.makeKeyAndVisible()

And in HomeViewController I push my OptionViewController like this:

    let optionsVC = OptionsViewController()
    navigationController?.pushViewController(optionsVC, animated: true)

The title does not show up!

enter image description here

The only way I've managed for the title to show up is by doing (in OptionViewController)

navigationController?.navigationBar.topItem?.title = "Route Options"

But it shows up as the back button rather than in the middle, which is not what I want.

enter image description here

If anyone could tell me how I could set the title so that it is on the middle of the navigation bar when it is pushed onto the navigationController stack that would be great!

Code

AppDelegate.swift

class AppDelegate: UIResponder, UIApplicationDelegate {
     func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        let rootVC = HomeViewController()
        let navigationController = UINavigationController(rootViewController: rootVC)
        let barAppearance = UINavigationBar.appearance()
        barAppearance.barTintColor = UIColor.blue
        barAppearance.tintColor = UIColor.white
        barAppearance.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
        self.window = UIWindow(frame: UIScreen.main.bounds)
        self.window!.rootViewController = navigationController
        self.window?.makeKeyAndVisible()

        return true
    }

HomeViewController.swift

class HomeViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, DestinationDelegate {
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
            let optionsVC = OptionsViewController()
            self.definesPresentationContext = false //else going to try and present optionVC on homeVC when in optionVC
            navigationController?.pushViewController(optionsVC, animated: true)
        }
        tableView.deselectRow(at: indexPath, animated: true)
    }
}

OptionsViewController.swift

class OptionsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource,
    DestinationDelegate, SearchBarCancelDelegate,UISearchBarDelegate,
    CLLocationManagerDelegate {
    override func viewDidLoad() {
        self.title = "Route Options"
    }

All you need is initialisation navigationItem.title by string containing any printable symbols in viewDidLoad function. String like "" or " " will not worked. Like this:

    override func viewDidLoad() {
        super.viewDidLoad()
        navigationItem.title = "."
    }

Then code navigationItem.title = "Any string" will work well anywhere in your ViewController.

This bag was fixed in iOs 16.2

Using Objective-C I also had the problem that it didn't show me the title but going to the next Scene the title appeared next to the back button.

I don't really know why, but I solved it by programming the relative ViewController of that Scene in Swift instead of Objective-C.

After that, it was enough to use the command:

self.title = "My Title"

and so I was able to write what I want programmatically, using if-statement or other methodologies.

Maybe this could be useful to someone who has this problem with Objective-C.

For others coming here based on the title, don't forget to set your ViewController class in IB to the appropriate Swift file.

After doing that I was able to set the title without a problem using

self.navigationItem.title = "my title"

or 

self.title = "my title"

Just add the below line to set the title for navigation item

self.title = "Title 1"

first you need to set UINavigationBar color and text color . try this in didFinishLaunchingWithOptions.

let barAppearance = UINavigationBar.appearance()
    barAppearance.barTintColor = UIColor.blue
    barAppearance.tintColor = UIColor.white
    barAppearance.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]

if you want to remove the string after backbutton add these too

let barItemAppearace = UIBarButtonItem.appearance()
    barItemAppearace.setBackButtonTitlePositionAdjustment(UIOffsetMake(0, -60), for:UIBarMetrics.default)

And just set your title in viewDidLoad() or

  override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    self.title = "Your Title"

}

Try it:

In HomeViewController:

let optionsVC = OptionsViewController()
navigationController?.viewControllers = [optionsVC]

And in your OptionsViewController:

override func viewDidLoad() {
        super.viewDidLoad()

        navigationController?.navigationBar.isTranslucent = false
        navigationItem.title = "Your Title"
    }

You need to set the navigationItem.title to desired value. If you want an image you set navigationItem.titleView

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.title = "Your title here"
 }
