This is a script for incrementing build numbers in xcode, automatically during the build phase. It handles the build in the format xx.yy.zz where zz is incremented for each build, and yy is incremented when you archive your project. The xx is handled manually in this case. For more information, you can read my blog post at http://bit.ly/1h3ztJK …
