xcode-new-empty-app.md

1. Create a new project in Xcode.
2. Select the "Single View Application" template.
3. Once created, delete the the files Main.storyboard, ViewController.h, ViewController.m
4. Go into your project settings (Command+1, then click on the project name at the top), and delete the text "Main" under "Main Interface".
5. Open AppDelegate.m and add in the missing window code. Your application:didFinishLaunchingWithOptions: method should look like:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}
