How to use UINavigationController programmatically
1. Make ios project no storyboard setting.
Here is my link to set no storyboard.

2. Set UINavigationController to start window's rootViewController
import UIKit
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
guard let windowScene = (scene as? UIWindowScene) else { return }
window = UIWindow(windowScene: windowScene)
let rootVC = ViewController()
let navVC = UINavigationController(rootViewController: rootVC)
window?.rootViewController = navVC
window?.makeKeyAndVisible()
}
}
