Issue/Introduction

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

Environment

CA APP EXPERIENCE ANALYTICS 16.4

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.
