We'll start the chapter by covering some of the new design principles present in iOS 7. This includes changes to the navigation and status bars, to the new UIKit, and changes to the application icon. Next, we will create our required files and organize them for easier navigation. Lastly, we will add some new view controllers to our storyboard and point them to our newly created files. On completing this chapter, we will have a complete skeleton of our application that is ready for functionality. Let's get started!
