Use Google Analytics to get metrics for crash reports

Google Analytics is Firebase's analytics engine. When you use Analytics and Crashlytics together in your app, you get features that help you produce issues and keep track of crash data with more granularity, such as crash-free users, breadcrumbs that track specific events prior to a crash, and BigQuery, where you can visualize your app's key metrics.

This guide describes how to add Analytics to an app that has Crashlytics set up (if you haven't already, add Crashlytics to your app).

Step 1: Add a Firebase configuration file

  1. Open your Project Settings. In the Your apps card, select the bundle ID of the app for which you need a config file.

  2. Click Download GoogleService-Info.plist to obtain your Firebase Apple platforms config file (GoogleService-Info.plist).

  3. Move your config file into the root of your Xcode project. If prompted, select to add the config file to all targets.

If you have multiple bundle IDs in your project, you must associate each bundle ID with a registered app in the Firebase console so that each app can have its own GoogleService-Info.plist file.

Step 2: Add the Analytics SDK to your app

Use Swift Package Manager to install and manage Firebase dependencies.

  1. In Xcode, with your app project open, navigate to File > Swift Packages > Add Package Dependency.
  2. When prompted, add the Firebase Apple platforms SDK repository:
    3.   https://github.com/firebase/firebase-ios-sdk
  3. Add the Firebase SDK for Google Analytics, selecting either the library with or the library without IDFA collection.
  4. When finished, Xcode will automatically begin resolving and downloading your dependencies in the background.

Next, configure the Firebase module:

  1. Import the FirebaseCore module in your UIApplicationDelegate, as well as any other Firebase modules your app delegate uses. For example, to use Cloud Firestore and Authentication:

    SwiftUI

    import SwiftUI
import FirebaseCore
import FirebaseFirestore
import FirebaseAuth
// ...

    Swift

    import FirebaseCore
import FirebaseFirestore
import FirebaseAuth
// ...

    Objective-C

    @import FirebaseCore;
@import FirebaseFirestore;
@import FirebaseAuth;
// ...
  2. Configure a FirebaseApp shared instance in your app delegate's application(_:didFinishLaunchingWithOptions:) method:

    SwiftUI

    // Use Firebase library to configure APIs
FirebaseApp.configure()

    Swift

    // Use Firebase library to configure APIs
FirebaseApp.configure()

    Objective-C

    // Use Firebase library to configure APIs
[FIRApp configure];
  3. If you're using SwiftUI, you must create an application delegate and attach it to your App struct via UIApplicationDelegateAdaptor or NSApplicationDelegateAdaptor. You must also disable app delegate swizzling. For more information, see the SwiftUI instructions.

    SwiftUI

    @main
struct YourApp: App {
  // register app delegate for Firebase setup
  @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate

  var body: some Scene {
    WindowGroup {
      NavigationView {
        ContentView()
      }
    }
  }
}

Your app is now set up to use Google Analytics.
