Could not find a storyboard named 'MainStoryBoard' in bundle NSBundle

Question

I have started a new app a few days ago and began working with the simulator to test it. I started as an empty project and manually added the storyboard. The simulator build

Answer 1

Update: Swift 5 and iOS 13:

1. Create a Single View Application.
2. Delete Main.storyboard (right-click and delete).
3. Delete Storyboard Name from the default scene configuration in the Info.plist file:
4. Open SceneDelegate.swift and change func scene from:

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 _ = (scene as? UIWindowScene) else { return }
}

to

 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).x

    if let windowScene = scene as? UIWindowScene {
        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = ViewController()
        self.window = window
        window.makeKeyAndVisible()
    }
}

Now you are good to go :)
