Answer 1

I suggest you can do two things:

• You could integrate a 3rd party crash reporting library such as Instabug which will help you get more details about the type of device, software version, CPU load, memory usage, and connectivity. All of which are important factors when it comes to debugging and reproducing the crash.

• The crash report is not symbolicated. You first have to locate your project's dSYM file. Type the line below in terminal so you can locate the file.

   mdfind "com_apple_xcode_dsym_uuids == your-UUID-here" 

  You can find your UUID written on top of the Instabug dashboard. You can then upload your dSYM file through the dashboard to get symbolicated crashes that are more comprehensible.

For full disclosure, I work at Instabug. Let me know if I can help.
