We got multiple crash events reported by our customers post-app update. The event is like the app got crashed upon the app launch. After reinstalling the app, it works for them. Here I have attached complete crash logs shared by our customers from their devices as well as from the Testflight crash logs console from Xcode. Here is the suspected code that causes the crash but we are not sure: Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0: 0 libsystem_kernel.dylib 0x2007c5b48 mach_msg2_trap + 8 1 libsystem_kernel.dylib 0x2007d8008 mach_msg2_internal + 80 2 libsystem_kernel.dylib 0x2007d8248 mach_msg_overwrite + 388 3 libsystem_kernel.dylib 0x2007c608c mach_msg + 24 4 libdispatch.dylib 0x1cb1b9364 _dispatch_mach_send_and_wait_for_reply + 540 5 libdispatch.dylib 0x1cb1b96ec dispatch_mach_send_with_result_and_wait_for_reply + 60 6 libxpc.dylib 0x210c7b2e4 xpc_connection_send_message_with_reply_sync + 240 7 Security 0x1cb9989b4 securityd_message_with_reply_sync + 124 8 Security 0x1cb9a2aa4 securityd_send_sync_and_do + 88 9 Security 0x1cba49598 cftype_to_bool_cftype_error_request + 160 10 Security 0x1cb992d4c __SecItemCopyMatching_block_invoke_2 + 200 11 Security 0x1cb995dc4 __SecItemAuthDoQuery_block_invoke + 532 12 Security 0x1cb994898 SecItemAuthDoQuery + 1236 13 Security 0x1cb995a94 __SecItemCopyMatching_block_invoke + 140 14 Security 0x1cb99b99c SecOSStatusWith + 56 15 Security 0x1cb99595c SecItemCopyMatching + 400 16 myappname 0x10273ec34 0x102188000 + 5991476 17 myappname 0x102473298 0x102188000 + 3060376 18 myappname 0x1023e0be0 0x102188000 + 2460640 19 myappname 0x1021d6f54 0x102188000 + 323412 20 myappname 0x10264cd8c 0x102188000 + 5000588 21 UIKitCore 0x1c60db810 -[UIApplication _handleDelegateCallbacksWithOptions:isSuspended:restoreState:] + 180 22 UIKitCore 0x1c60dafac -[UIApplication _callInitializationDelegatesWithActions:forCanvas:payload:fromOriginatingProcess:] + 2848 23 UIKitCore 0x1c60d9f88 -[UIApplication _runWithMainScene:transitionContext:completion:] + 856 24 UIKitCore 0x1c60d9bd4 -[_UISceneLifecycleMultiplexer completeApplicationLaunchWithFBSScene:transitionContext:] + 132 25 UIKitCore 0x1c5e1f600 _UIScenePerformActionsWithLifecycleActionMask + 108 26 UIKitCore 0x1c6161918 __101-[_UISceneLifecycleMultiplexer _evalTransitionToSettings:fromSettings:forceExit:withTransitionStore:]_block_invoke + 216 Kindly help here to get it resolved.
