App starts with black screen in iPhone

Question

I changed "Launch Screen File" to my "Main.Storyboard" in settings. Before doing this app was working fine, and opened directly without any problem. But after adding this there was a black screen before the launch of storyboard. This is very bad user experience. Help me to solve this. AppDelegate and viewController has nothing big. I have a LaunchScreen.xib in project and also LaunchImage in image assets. I am using Storyboard in project. I don't want a launchScreen in my app, I just wanna directly go to my storyboard.

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

 self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        self.window?.rootViewController = utilitiesObjet.getViewController("MainVC", mainStoryBoardName: "Main")
        self.window?.makeKeyAndVisible()

        Fabric.with([Crashlytics.self()])

        return true
    }

I solved it by adding a LaunchScreen.StoryBoard, Instead of using a LaunchScreen.xib. Thank you All :)

This may be because there is an outlet on your storyboard's initial view cotroller, which will cause nothing to render. Nothing will also happen if your initial view controller is a navigation controller. — Matt Le Fleur

use this code in appdelegate this code for objective c .....did finish launching with option method...

        self.winow = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen]bounds]];

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"<Your Storyboard name>" bundle:nil];
        LoginViewController *ivc = [storyboard instantiateViewControllerWithIdentifier:@"<your view controller storyboard identifer name>"];
        UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:ivc];

        self.window.rootViewController = navigationController;
        [self.window makeKeyAndVisible];

For Swift....

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    // Override point for customization after application launch.
    let storyboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let navigationController:UINavigationController = storyboard.instantiateInitialViewController() as UINavigationController
    let rootViewController:UIViewController = storyboard.instantiateViewControllerWithIdentifier("VC") as UIViewController
    navigationController.viewControllers = [rootViewController]
    self.window?.rootViewController = navigationController
    return true
}
