starting ios project without storyboard

Question

Im having some troubles to start an iOS app using xibs instead of storyboard. The problem is that im getting a black screen and the first view controller is not being called

Answer 1

Xcode 11 with SceneDelegate

In SceneDelegate.m

- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)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).
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.windowScene = (UIWindowScene *)scene;
self.viewController = [[ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
}

No need to do anything in AppDelegate.m
