A simple app to browse your Glyphish icons and just drag and drop them straight into Xcode.
Clone the repository and build in Xcode. Put your Glyphish icons in a folder and point the app to that folder. Done.
The binary is included in the package if you don't want to build it yourself. Enjoy!
The license is free to do whatever you do as long as you don't violate the Glyphish copyright.
