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

Objective-C

Import GoogleDataTransport:

#import <GoogleDataTransport/GoogleDataTransport.h>

Set logging level global variable to the desired value before calling -[FIRApp config]:
```
GDTCORConsoleLoggerLoggingLevel = GDTCORLoggingLevelDebug;
```

Prereqs

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

To develop

Run generate_project.sh after installing the prereqs

When adding new logging endpoint

Use commands similar to:
- python -c "line='https://www.firebase.com'; print line[0::2]"
- python -c "line='https://www.firebase.com'; print line[1::2]"

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

Consider using go/copybara-library/scrubbing#cc_scrub

Development

Ensure that you have at least the following software:

Xcode 12.0 (or later)
CocoaPods 1.10.0 (or later)
CocoaPods generate

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Note: If the CocoaPods cache is out of date, you may need to run pod repo update before the pod gen command.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/check.sh 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 clang-format@11
brew install mint

Running Unit Tests

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