Splunk AppDynamics requires the dSYM file for the application to produce human-readable stack traces for crash snapshots. For details about the importance of snapshots, see Get Human-Readable Crash Snapshots.

If you update the application, you are required to provide the new dSYM file for the new application version. The dSYM file contains a UUID that links it to a specific Xcode build, so Splunk AppDynamics can unambiguously match the correct dSYM file with an incoming crash report with no additional information.

To upload the dSYM file:

1. Enable the dSYM file.

2. Set up your environment to upload the file automatically each time you build or upload the file manually.
