I use the Crashlytics framework for crash collecting in iOS Apps.
When you use the framework, a "Build Phase" is added to your target that runs
/Fabric/Fabric.framework/run <big-hex-blob> <another-even-biger-hex-blob>
Mike from Crashlytics and Fabric here.
The run script build phase is used, along with your
<APIkey> and <BuildSecret>, to automatically handle the uploading of dSYMs so that you, and other developers, never need to manually upload one.
/Crashlytics.framework/submit command is used for distributions through Beta, our beta distribution service.
