Add Firebase to your Apple project

Prerequisites

  • Install the following:

    • Xcode 15.2 or later

  • Make sure that your project meets these requirements:

    • Your project must target these platform versions or later:
      • iOS 13
      • macOS 10.15
      • tvOS 13
      • watchOS 7

  • Set up a physical Apple device or use a simulator to run your app.

If you don't already have an Xcode project and just want to try out a Firebase product, you can download one of our quickstart samples.

Step 1: Create a Firebase project

Before you can add Firebase to your Apple app, you need to create a Firebase project to connect to your app. Visit Understand Firebase Projects to learn more about Firebase projects.

Step 2: Register your app with Firebase

To use Firebase in your Apple app, you need to register your app with your Firebase project. Registering your app is often called "adding" your app to your project.

  1. Go to the Firebase console.

  2. In the center of the project overview page, click the iOS+ icon to launch the setup workflow.

    If you've already added an app to your Firebase project, click Add app to display the platform options.

  3. Enter your app's bundle ID in the bundle ID field.

  4. (Optional) Enter other app information: App nickname and App Store ID.

  5. Click Register app.

Step 3: Add a Firebase configuration file

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

  2. 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 4: Add Firebase SDKs to your app

Use Swift Package Manager to install and manage Firebase dependencies.

  1. In Xcode, with your app project open, navigate to File > Add Packages.
  2. When prompted, add the Firebase Apple platforms SDK repository:
    3.   https://github.com/firebase/firebase-ios-sdk
  3. Select the SDK version that you want to use.

  4. Choose the Firebase libraries you want to use.

    If Google Analytics is enabled in your Firebase project, make sure to add FirebaseAnalytics. For Analytics without IDFA collection capability, add FirebaseAnalyticsWithoutAdId instead.

When finished, Xcode will automatically begin resolving and downloading your dependencies in the background.

Step 5: Initialize Firebase in your app

The final step is to add initialization code to your application. You may have already done this as part of adding Firebase to your app. If you're using a quickstart sample project, this has been done for you.

  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()
      }
    }
  }
}
  4. If you've included the Firebase SDK for Google Analytics, you can run your app to send verification to the Firebase console that you've successfully installed Firebase.

That's it! You can skip ahead to the next steps.

If you're having trouble getting set up, though, visit the Apple platforms troubleshooting & FAQ.

Integrate without using Swift Package Manager

If you don't want to use Swift Package Manager, you can still take advantage of the Firebase SDKs by using CocoaPods or by importing the frameworks directly.

CocoaPods

Learn more about CocoaPods integration in our guide.

Frameworks

In addition to supporting the iOS platform, the zip now includes .xcframework files. For details, see the Firebase Apple platforms SDK README on GitHub .

  1. Download the framework SDK zip. This is a ~200MB file and might take some time to download.

  2. Unzip the file, and then integrate the frameworks that you want to include in your app.

    You can find integration instructions in either of the following places:

    For information regarding framework versions or dependencies, refer to the METADATA.md file within the downloaded zip distribution.

  3. Add the -ObjC linker flag in your Other Linker Settings in your target's build settings.
