Look up the iOS API key for your project on the [Credentials](https://console.cloud.google.com/apis/credentials?project=_)\n page of the **APIs \\& Services** section of the Google Cloud console.\n\n2. In your debug build, configure App Check to use the debug provider. You'll\n need to specify the API key you got in the previous step.\n\n #if targetEnvironment(simulator)\n GIDSignIn.sharedInstance.configureDebugProvider(withAPIKey: apiKey) { error in\n if let error {\n print(\"Error configuring `GIDSignIn` for App Check: \\(error)\")\n }\n }\n #else\n // Configure App Check for production.\n #endif\n\n3. Launch the app. A local debug token will be logged to the Xcode console when\n the SDK tries to send a request to the backend. For example:\n\n \u003cWarning\u003e [AppCheckCore][I-GAC004001] App Check debug token:\n '123a4567-b89c-12d3-e456-789012345678'.\n\n4. In the [App Check](https://console.firebase.google.com/project/_/appcheck) section\n of the Firebase console, choose **Manage debug tokens** from your app's\n overflow menu. Then, register the debug token you logged in the previous\n step.\n\nAfter you register the token, Google's OAuth 2.0 endpoints will accept it as\nvalid for your project.\n\nBecause this token allows access to your auth endpoints without a\nvalid device, it is crucial that you keep it private. Don't commit it to a\npublic repository, and if a registered token is ever compromised, revoke it\nimmediately in the Firebase console.\n\nUse the debug provider in a CI environment\n------------------------------------------\n\nTo use the debug provider in a continuous integration (CI) environment, do the\nfollowing:\n\n1. In the [App Check](https://console.firebase.google.com/project/_/appcheck) section\n of the Firebase console, choose **Manage debug tokens** from your app's\n overflow menu. Then, create a new debug token. You'll need the token in the\n next step.\n\n Because this token allows access to your auth endpoints without\n a valid device, it is crucial that you keep it private. Don't commit it to a\n public repository, and if a registered token is ever compromised, revoke it\n immediately in the Firebase console.\n\n2. Add the debug token you just created to your CI system's secure key store\n (for example, GitHub Actions' [encrypted secrets](https://docs.github.com/en/actions/reference/encrypted-secrets)\n or Travis CI's [encrypted variables](https://docs.travis-ci.com/user/environment-variables/#defining-encrypted-variables-in-travisyml)).\n\n3. If necessary, configure your CI system to make your debug token available\n within the CI environment as an environment variable. Name the variable\n something like `APP_CHECK_DEBUG_TOKEN_FROM_CI`.\n\n4. In Xcode, add an environment variable to your testing scheme with the name\n `FIRAAppCheckDebugToken` and something like `$(APP_CHECK_DEBUG_TOKEN)` as\n the value.\n\n5. Configure your CI test script to pass the debug token as an environment\n variable. For example:\n\n ```\n xcodebuild test -scheme YourTestScheme -workspace YourProject.xcworkspace \\\n APP_CHECK_DEBUG_TOKEN=$(APP_CHECK_DEBUG_TOKEN_FROM_CI)\n ```\n6. Look up the iOS API key for your project on the [Credentials](https://console.cloud.google.com/apis/credentials?project=_)\n page of the **APIs \\& Services** section of the Google Cloud console.\n\n7. In your debug build, configure App Check to use the debug provider. You'll\n need to specify the API key you got in the previous step.\n\n #if targetEnvironment(simulator)\n GIDSignIn.sharedInstance.configureDebugProvider(withAPIKey: apiKey) { error in\n if let error {\n print(\"Error configuring `GIDSignIn` for App Check: \\(error)\")\n }\n }\n #else\n // Configure App Check for production.\n #endif\n\nWhen your app runs in a CI environment, Google's OAuth 2.0 endpoints will accept\nthe token it sends as valid for your project."]]
