How to add navigation controller programmatically, i'm using XIB file swift

Question

i want to create navigation bar but nothing happens

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    let viewController = DummyViewController(nibName: nil, bundle: nil) 
    let navigationController = UINavigationController(rootViewController: viewController)

    self.window = UIWindow(frame: UIScreen.main.bounds)
    self.window?.rootViewController = navigationController
    self.window?.makeKeyAndVisible()

    let tabBarController = UITabBarController()
    let tabViewController1 = DummyViewController(
        nibName: "DummyViewController",
        bundle: nil)
    let tabViewController2 = SearchViewController(
        nibName:"SearchViewController",
        bundle: nil)

    tabViewController1.tabBarItem = UITabBarItem(
        title: "Location",
        image: UIImage(named: "ic_location_blue"),
        tag: 1)
    tabViewController2.tabBarItem = UITabBarItem(
        title: "Search",
        image:UIImage(named: "ic_search_blue") ,
        tag:2)


    let controllers = [tabViewController1,tabViewController2]
    tabBarController.viewControllers = controllers
    window?.rootViewController = tabBarController

    return true
}

it seems because i add self.window?.rootViewController = navigationController and window?.rootViewController = tabBarController

i'm using xib file, and don't know how to use tab bar controller with navigation controller together, thanks before.

Then programatically OR in xib?

you could try this

let viewController = DummyViewController(nibName: nil, bundle: nil)
let navigationController = UINavigationController()
navigationController.viewControllers = [viewController!]
self.window!.rootViewController = navigationController
self.window?.makeKeyAndVisible()

Hope it helps.

solved using

let FirstViewController: HomeViewController = HomeViewController(nibName: "HomeViewController", bundle: nil)
    let navigationBarFirst = UINavigationController(rootViewController: FirstViewController)

    let SecondViewController: SearchViewController = SearchViewController(nibName: "SearchViewController", bundle: nil)
    let navigationBarSecond = UINavigationController(rootViewController: SecondViewController)

    let ThirdViewController: InformationViewController = InformationViewController(nibName: "InformationViewController", bundle: nil)
    let navigationBarThird = UINavigationController(rootViewController: ThirdViewController)

    let FourthViewController: FavoritesViewController = FavoritesViewController(nibName: "FavoritesViewController", bundle: nil)
    let navigationBarFourth = UINavigationController(rootViewController: FourthViewController)

    let FifthViewController: MenuViewController = MenuViewController(nibName: "MenuViewController", bundle: nil)
    let navigationBarFifth = UINavigationController(rootViewController: FifthViewController)

    let tabBarController = UITabBarController()

    let controllers = [navigationBarFirst, navigationBarSecond, navigationBarThird, navigationBarFourth, navigationBarFifth]

You are writing the nil as nib name. Enter the nib name as follows:-

let viewController = DummyViewController(nibName: "DummyViewController", bundle: nil)
