Creating a navigationController programmatically (Swift)

Question

I\'ve been trying to redo the work on my app programmatically. (Without the use of storyboards)

I\'m almost done, except making the navigation controller manually.

Answer 1

 self.window = UIWindow(frame: UIScreen.main.bounds) 
 let storyboard = UIStoryboard(name: "Main", bundle: nil) 
 let storyboard_Secondary = UIStoryboard(name: "Secondary", bundle: nil) 
 var initialViewController = UIViewController() 

 let aUser = CommonMethods.loadCustomObject("\(Constants.kUserProfile)") as? User  
 if aUser?.respCode == 1 { 
    initialViewController = storyboard_Secondary.instantiateViewController(withIdentifier: "MainTabVC")
    UIApplication.shared.statusBarStyle = .lightContent
    let navigationController = UINavigationController(rootViewController: initialViewController)
    navigationController.isNavigationBarHidden = true
    self.window!.rootViewController = navigationController
    self.window!.makeKeyAndVisible() 
}
