Unreadble errors with Firebase Crash Reporting on ios (Symbol files)

I'm using firebase crash reporting to get crash on my iphone project.

But the logs that I receive are not readable :

Exception name: EXC_BREAKPOINT / EXC_ARM_BREAKPOINT

This is an issue with firebase or apple errors ?

In my Build Phases on my project, I have this script :

# Replace this path with the path to the key you just downloaded

JSON_FILE=/*****/TPC_Swift/TPC_swift/TPC_swift/Project-*****.json

# Replace this with the GOOGLE_APP_ID from your GoogleService-Info.plist file
GOOGLE_APP_ID=1:*********:ios:***************

defaults write com.google.SymbolUpload version -integer 1   # creates file if it does not exist
JSON=$(cat "${JSON_FILE}")
/usr/bin/plutil -replace "app_${GOOGLE_APP_ID//:/_}" -json "${JSON}" "$HOME/Library/Preferences/com.google.SymbolUpload.plist"
"${PODS_ROOT}"/FirebaseCrash/upload-sym

Thank you

EDIT :

On firebase, I have :

Upload symbol file to symbolicate future stack traces for UUID 68FD2AAC-F8A7-***********

I think the issue is linked to the symbol files How to solve this ?

EDIT 2 :

I tried "dwarfdump --uuid /path/to/your/build/area/MyApp.app/MyApp" but I can not retrieved this UUID...

Solution

Did you find the answer for your question?

Your script seems to be a little different than the one recommended at the Firebase doc today (Sep 18 2016).

Have you tried this one?

# Replace this with the GOOGLE_APP_ID from your GoogleService-Info.plist file
GOOGLE_APP_ID=1:my:app:id

# Replace the /Path/To/ServiceAccount.json with the path to the key you just downloaded
"${PODS_ROOT}"/FirebaseCrash/upload-sym "/Path/To/ServiceAccount.json"
