The application:didFinishLaunchingWithOptions: method in XYZAppDelegate.m is the first method in the file,which contains some lines of code that set up the app window and give it the white background color you saw when you ran your app for the first time.

Now you need to tell Xcode that you want to use this storyboard as the interface to your app. When it starts up, the application object checks whether the app has a main interface configured. If it does, the application object loads the defined storyboard when the app launches.
