This is a Photoshop document that, through Smart Objects, automates the process of rendering the various sizes that needs to be bundled with iOS Apps. The idea is to edit the largest size and have the smaller sizes automatically rendered, enabling a much quicker workflow when designing icons. You’ll also find a selection of iOS specific colors and shapes that you can build on, enviroment previews and easy export actions that spit out the exact files you need to deliver to Apple.
