Actions Status


This library is for internal Google use only. It allows the logging of data and telemetry from Google SDKs.

Integration Testing

These instructions apply to minor and patch version updates. Major versions need a customized adaptation.

After the CI is green:

  • Update the version in the podspec
  • Add the CocoaPods tag
    • git tag CocoaPods-{version}
    • git push origin CocoaPods-{version}
  • Push the podspec to SpecsStaging
    • pod repo push staging GoogleDataTransport.podspec
  • Run Firebase CI by waiting until next nightly or adding a PR that touches Gemfile
  • On google3, copybara and run a global TAP which should kick off automatically after each PR.


  • Add a version tag for Swift PM
    • git tag {version}
    • git push origin {version}
  • pod trunk push GoogleDataTransport.podspec
  • Clean up SpecsStaging

Set logging level


  • Import GoogleDataTransport module:
    import GoogleDataTransport
  • Set logging level global variable to the desired value before calling FirebaseApp.config():
    GDTCORConsoleLoggerLoggingLevel = GDTCORLoggingLevel.debug.rawValue


  • Import GoogleDataTransport:
    #import <GoogleDataTransport/GoogleDataTransport.h>
  • Set logging level global variable to the desired value before calling -[FIRApp config]:
    GDTCORConsoleLoggerLoggingLevel = GDTCORLoggingLevelDebug;


  • gem install --user cocoapods cocoapods-generate
  • brew install protobuf nanopb-generator
  • easy_install --user protobuf

To develop

  • Run after installing the prereqs

When adding new logging endpoint

  • Use commands similar to:
    • python -c "line=''; print line[0::2]"
    • python -c "line=''; print line[1::2]"

When adding internal code that shouldn't be easily usable on github

  • Consider using go/copybara-library/scrubbing#cc_scrub


Ensure that you have at least the following software:

For the pod that you want to develop:

pod gen GoogleDataTransport.podspec --local-sources=./ --auto-open --platforms=ios

Note: If the CocoaPods cache is out of date, you may need to run pod repo update before the pod gen command.

Note: Set the --platforms option to macos or tvos to develop/test for those platforms. Since 10.2, Xcode does not properly handle multi-platform CocoaPods workspaces.

Development for Catalyst

  • pod gen GoogleDataTransport.podspec --local-sources=./ --auto-open --platforms=ios
  • Check the Mac box in the App-iOS Build Settings
  • Sign the App in the Settings Signing & Capabilities tab
  • Click Pods in the Project Manager
  • Add Signing to the iOS host app and unit test targets
  • Select the Unit-unit scheme
  • Run it to build and test

Alternatively disable signing in each target:

  • Go to Build Settings tab
  • Click +
  • Select Add User-Defined Setting
  • Add CODE_SIGNING_REQUIRED setting with a value of NO

Code Formatting

To ensure that the code is formatted consistently, run the script ./scripts/ before creating a PR.

GitHub Actions will verify that any code changes are done in a style compliant way. Install clang-format and mint:

brew install [email protected]
brew install mint

Running Unit Tests

Select a scheme and press Command-u to build a component and run its unit tests.
