Firebase App Check provider that verifies app integrity using the DeviceCheck API. This class is available on all platforms for select OS versions. See https://firebase.google.com/docs/ios/learn-more for more details.

A class used to manage app check tokens for a given Firebase app.

A Firebase App Check provider that can exchange a debug token registered in the Firebase console for a Firebase App Check token. The debug provider is designed to enable testing applications on a simulator or test environment.

NOTE: Do not use the debug provider in applications used by real users.

WARNING: Keep the Firebase App Check debug token secret. If you accidentally share one (e.g. commit to a public source repo), remove it in the Firebase console ASAP.

To use AppCheckDebugProvider on a local simulator:

1. Configure AppCheckDebugProviderFactory before FirebaseApp.configure(): AppCheck.setAppCheckProviderFactory(AppCheckDebugProviderFactory()) 2. Enable debug logging by adding the -FIRDebugEnabled launch argument to the app target. 3. Launch the app. A local debug token will be logged when Firebase is configured. For example: “[Firebase/AppCheck][I-FAA001001] Firebase App Check Debug Token: ‘3BA09C8C-8A0D-4030-ACD5-B96D99DB73F9’”. 4. Register the debug token in the Firebase console.

Once the debug token is registered the debug provider will be able to provide a valid Firebase App Check token.

To use AppCheckDebugProvider on a simulator on a build server:

1. Create a new Firebase App Check debug token in the Firebase console
2. Add the debug token to the secure storage of your build environment. E.g. see Encrypted secrets for GitHub Actions, etc.
3. Configure AppCheckDebugProviderFactory before FirebaseApp.configure() AppCheck.setAppCheckProviderFactory(AppCheckDebugProviderFactory())
4. Add an environment variable to the scheme with a name FIRAAppCheckDebugToken and value like $(MY_APP_CHECK_DEBUG_TOKEN).
5. Configure the build script to pass the debug token as the environment variable, e.g.: xcodebuild test -scheme InstallationsExample -workspace InstallationsExample.xcworkspace \ MY_APP_CHECK_DEBUG_TOKEN=$(MY_SECRET_ON_CI)

An implementation of AppCheckProviderFactory that creates a new instance of DeviceCheckProvider for the specified FirebaseApp on request. Currently DeviceCheckProviderFactory is the default that will be used by Firebase App Check if no other provider is specified. See AppCheck class for more details.
