We previously covered the power of the offline bundle.
If you still don't know anything about it, then check Using offline bundle on the official docs.

At this point, you're ready to know that's what the AppHub's folks have put on steroids.

Include our code snippet to connect to AppHub

[AppHub setApplicationId:@"APPLICATION_ID"];
NSBundle *bundle = [AppHub currentBuild].bundle;
NSURL *jsCodeLocation = [bundle URLForResource:@"main"
                                 withExtension:@"jsbundle"];

Submit to the Apple App Store

Celebrate! This is the last time you'll have to wait for Apple review.
