Through this project, I have learnt how to programmatically build a navigation bar and its main components

iOS Version

This NavigationBar was built and run on iOS 15.0

Initial setup

1. Go to info

   • Select 'Main storyboard file base name'
   • Delete it

2. Go to Application Scene Manifest

   • Open it up until you get to 'Storyboard Name'
   • Delete it

3. Go to Xcode sidebar

   • Delete the main storyboard 'main'

4. Go to the 'SceneDelegate' file, inside the scene function, remove the existing and copy paste the following code;

    guard let windowScene = (scene as? UIWindowScene) else {return}
    let window = UIWindow(windowScene: windowScene)
    
    let vc = ViewController()
    let nav = UINavigationController(rootViewController: vc)
    
    window.rootViewController = nav
    
    self.window = window
    self.window?.makeKeyAndVisible()
