I have removed the authentication.
Thanks. Now that I can see your crash log, it’s clear that you’re suffering from a well known issue. Check out this line in your crash report:
Termination Reason: Namespace RUNNINGBOARD, Code 0xdead10cc
You can read 0xdead10cc as deadlock, and it indicates that your app has been killed by the system because it suspended while holding a file lock of some form. See Technote 2151 Understanding and Analyzing iOS Application Crash Reports for some general background on this.
Share and Enjoy
