I received a crash log with an error which I can't reproduce. Only information I got was that it happened after login, so I guess that it was on main screen. Any ideas if that log contains useful information?

I know this question might sound stupid but I hope to understand what is the problem in this crash report that generated in Xcode. I have no idea which view controller/page or which feature it crashes at. How to study a crash report? Anyone please help..

Apparently an App I submitted for review crashed twice on an iPad, with the following issue highlighted. I'm having trouble deciphering anything usable from this, if anyone's able to shed some light on this I'd appreciate it. I've attempted to replicate the issue using the simulator's but I've been unsuccessful. I don't understand how this could work on an iPhone, whilst testing, but not on the iPad.

I have only a little knowledge on how to read the crash reason in device logs. Please give me some clue on where should I start to look at in my app. It crashed the minute I clicked on a button when I open the app. I only got this error when I unplugged the device. I cannot reproduce the device if I try to build with my phone via Xcode.
Thank you.

It says that thread 11 is crashed but this looks like main thread crash as I can see from last line. The thread 11 stack trace looks like this
Thread 11 Crashed:
0 libsystem_kernel.dylib 0x3c4a4d98 __workq_kernreturn + 8
1 libsystem_c.dylib 0x3c3f2cf6 _pthread_workq_return + 14

Also the crash report points out that app was crashed while doing enumeration but I am not sure how it is related to UIView and UITableView objects as I see from the stack trace. Some more info, I have tableview which shows a list if data, this is fetched from server.
Can some help me in fixing this issue?
Thanks
#nkd, why not use a Crash Reporting Manager like , Crashlytics it does a two step symbolication process, once at the app, and at the server side, to give you exact location of your crash with all thread information, testing environment etc.
I have been using this extensively, helps a lot in resolving bugs.
