Ios – Firebase Upload missing required dSYMs Not Working

I had the same problem. The reason was that the script "$ {PODS_ROOT}/Fabric/run" was not the last in the list of scripts in Build Phases. Made the script last and everything became OK.

As of May 2020:

After Fabrics shut down, many developers faced such issues because Fabric was automatically creating the script to upload dSYM files from Xcode and we never pay attention to it.

Now as Fabric is replaced with FirebaseCrashlytics, in order to achieve this automatic mechanism, you can create a new run script and paste this script there:

"${PODS_ROOT}/FirebaseCrashlytics/upload-symbols" -gsp "${PROJECT_DIR}/GoogleService-Info.plist" -p ios "${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}"

This script will get the dSYM files and upload them to firebase servers so that you can see the crashes.

For multiple Schemes:

If your project has multiple schemes, you can simply create multiple such scripts by changing the path to the Google Plist file.

NOTE: You can also manually upload the dSYM files using upload-symbols tool [Check here], but it's always better to automate the process wherever we can.

EDIT: July 2020: When you see missing dSYM files for the crash in the Crashlytics dashboard, instead of getting the email for it, you can upload the dSYM file for the build as soon as you submit it for Apple review or for testing via Test Flight.

Missing dSYM is shown because when bitCode is enabled, the App Store Connect process the binary post uploading it and generates a new dSYM file.

You can find the dSYM file from the Activity section in the App Store Connect.
