I have followed proper steps for firebase crash reporting integration but I still have errors like this,
/Users/satish/Desktop/firebase_crash/Pods/FirebaseCrash/upload-sym:174: error: Please ensure you've followed the steps at:: command not found
/Users/satish/Desktop/firebase_crash/Pods/FirebaseCrash/upload-sym:175: error: https://firebase.google.com/docs/crash/ios#upload_symbol_files: No such file or directory
/Users/satish/Desktop/firebase_crash/Pods/FirebaseCrash/upload-sym:197: error: All attempts to find the service account JSON file have failed.
Here is the another way to fix this issue.
Run the command in terminal
https://firebase.google.com/docs/crash/ios#set_up_crash_reporting
Happy to help :)
Solved in Xcode 8.3.1 with replacing upload-sym with upload-sym-util.bash in script
new script
