Released app crashing with no clues

Question

I have a released app that is crashing. Below is a sample of one of the available crash logs that keeps telling me about the crash, however I cannot figure out where in my code this crash is occuring.Does anyone have any suggestions? It is working fine on all my devices.Thread 0 Crashed:0   MyApp                      0x000000010010daa4 0x1000f4000 + 1051241   MyApp                      0x000000010010db04 0x1000f4000 + 1052202   MyApp                      0x000000010010cda0 0x1000f4000 + 1017923   UIKit                         0x0000000188a89324 -[UIApplication _handleDelegateCallbacksWithOptions:isSuspended:restoreState:] + 400 (UIApplication.m:1789)4   UIKit                         0x0000000188cb7acc -[UIApplication _callInitializationDelegatesForMainScene:transitionContext:] + 2904 (UIApplication.m:2023)5   UIKit                         0x0000000188cbbe0c -[UIApplication _runWithMainScene:transitionContext:completion:] + 1656 (UIApplication.m:3253)6   UIKit                         0x0000000188cb8f50 -[UIApplication workspaceDidEndTransaction:] + 168 (UIApplication.m:2648)7   FrontBoardServices             0x000000018d29f7c4 -[FBSSerialQueue _performNext] + 184 (FBSSerialQueue.m:157)8   FrontBoardServices             0x000000018d29fb44 -[FBSSerialQueue _performNextFromRunLoopSource] + 56 (FBSSerialQueue.m:204)9   CoreFoundation                 0x0000000183438544 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 24 (CFRunLoop.c:1761)10  CoreFoundation                 0x0000000183437fd8 __CFRunLoopDoSources0 + 540 (CFRunLoop.c:1807)11  CoreFoundation                 0x0000000183435cd8 __CFRunLoopRun + 724 (CFRunLoop.c:2536)12  CoreFoundation                 0x0000000183364ca0 CFRunLoopRunSpecific + 384 (CFRunLoop.c:2814)13  UIKit                         0x0000000188a821c8 -[UIApplication _run] + 460 (UIApplication.m:2489)14  UIKit                         0x0000000188a7cffc UIApplicationMain + 204 (UIApplication.m:3665)15  PGW                           0x000000010010d2c8 0x1000f4000 + 10311216  libdyld.dylib                 0x00000001988828b8 start + 4 (start_glue.s:80)

You need to symbolicate the crashlog. Those lines 0, 1, 2 are in your app&#x27;s code and should help you to figure out the exact line that is crashing. Also, you don&#x27;t say what kind of crash: SIGABRT, SIGSEGV?

Apparently, symbolicating the crashlog is not working as it should in xcode as I have downloaded the dSyms in Archives the Organizer window and clicked Open in Project... in the Crashes tab of the Organizer window and it gives only this below. Also these are only reported crashes by users via email and all I have to go on now is the Crashes listed in the Organizer window.0 0x1000f40001 0x1000f40002 0x1000f40003 -[UIApplication _handleDelegateCallbacksWithOptions:isSuspended:restoreState:]What am I missing? Where can I find better documentation of a video ofsymbolicating the crashlog? The app was released using XCode 7 deployment target 9.0. I have sinced updated xcode to 7.1.1. Also, the type of crash was Exception Type:  EXC_BREAKPOINT (SIGTRAP)

Looks like maybe the app is timing out and being killed by the OS.Did you check memory use via Instruments?As well, try testing an ad-hoc build, which seems to replicated a store install more closely.

Hey I also face a similar issue with no clue on how to resolve it. Did you ever find any solution to this?
