I have begun creating an extension for Photoshop CC 2014 to make creating the layer names for Assetifier a breeze.
Here is two Psd to improve you App Icon workflow for iOS and Android.
Just open the psd files, enable Generator, and you files will automatically be exported for you.
Double click the “MASTER” smart object to edit your artwork.
*** UPDATE ***
Now supports the new iPhone 6, iPhone 6 plus, iPad Pro images.
note: for iPad Pro you just need to name those files the same as the iPad retina files and include those instead. Source for this info at http://forum.starling-framework.org/topic/ipad-pro-support
Just open, edit the smart object and remember to enable Generator :)
Put the Images in your project src folder.
