A coworker handed me an iPhone that crashed in the middle of our app running. The crash report credits the crash to mc_mobile_tunnel rather than our application.

What is mc_mobile_tunnel, and why is it taking out my application?


I think symbolizing your crash-log would give you more insight as where exactly the problem might be. See this post for how to do it: How to interpret a crashlog with no references to a specific class

However you need the dSYM Bundle which you get when you build the application (it's right next to your App in the build folder).

Example:

Another side remark there is a free service, which I consider to be a must-have, called Testflight which is really great for beta testing as it stores the crash logs online and can also do the symbolization for you.
