Symptoms
First, follow the instructions here: How do I symbolicate mobile crash reports?
The dSYM file has been uploaded and the upload has been verified, but the corresponding crash reports do not get symbolicated.
Diagnosis
If the dSYM file is incomplete or does not have the necessary debug information, the EUM Server will not be able to symbolicate the crash reports.
Use the "dwarfdump" command to verify that the dSYM file contains debugging information.
Example of output:
$ dwarfdump 86D24-73RC-2B32-ZY70-ABCXYZ.dSYM
----------------------------------------------------------------------
File: 86D24-73RC-2B32-ZY70-ABCXYZ.dSYM (arm64)
----------------------------------------------------------------------
.debug_info contents:
< EMPTY >
Solution
Check that the dSYM file is complete and contains the necessary debugging information prior to upload.
