From the developer:
Cella is an application that allows you to create icons for iOS devices. Xcode 5 asks developers for 18 icon images to use for Universal apps. Cella creates these icons from your single 1024×1024 image. It outputs the 18 sizes for you to drag into your Xcode project. These icons should be automatically detected by Xcode 5 and set for you in the General settings. If not, you may need to select the icon images manually.
