Issue:

 Unknown crash types for iOS mobile app version 8.2.1 in CA AXA 16.4.

Environment:
CA APP EXPERIENCE ANALYTICS 16.4
Cause:

 Some particular crashes do not have symbolicating that was caused by the way that we upload/handle .dSym files. In the current symbolication implementation, we only symbolicate crashes from Application space/threads. These crashes are on some library called TCC as shown below and in the symbolicated crash log below, and AXA is not able to group crashes properly;

2 TCC 0x0000000188c52560 __TCCAccessRequest_block_invoke_2.80 + 0
3 TCC 0x0000000188c5245c __CRASHING_DUE_TO_PRIVACY_VIOLATION__ + 0
4 TCC 0x0000000188c5552c __tccd_send_block_invoke + 288

Resolution:

An enhancement has been raised to Sustaining Engineering, re-architecting on AXA for uploading .dSym files, symbolicating the crash logs, and allow to view the crashes in AXA UI in a later version.
