iOS setup guide

warning

If you use Expo, follow this guide instead. This guide applies to vanilla React Native apps only.

  • run pod install in ios/ directory to install the module

Google project configuration​

  • Follow this guide to get the configuration information which you need for the next steps.

Firebase Authentication​

If you're using Firebase Authentication, download the GoogleService-Info.plist file and place it into your Xcode project.

Xcode configuration​

  • Configure URL types in the Info panel (see screenshot)
    • add your "iOS URL scheme" (also known as reversed client id), which can be found in Google Cloud Console under your iOS client ID.
  • If you need to support Mac Catalyst, you will need to enable the Keychain Sharing capability on each build target. No keychain groups need to be added.

Rebuild the native project​

Do not forget to rebuild the native app after the setup is done.

Optional: modify your app to respond to the URL scheme​

This is only required if you have multiple listeners for openURL - for instance if you have both Google and Facebook OAuth.

Because only one openURL method can be defined, if you have multiple listeners for openURL, you must combine them into a single function as shown below:

For AppDelegate written in Swift​

If your AppDelegate a Swift file (the default in React Native 0.77.0 or higher), you'll need to:

  1. Add the following import to your project's bridging header file (usually ios/YourProject-Bridging-Header.h):
// …

// ⬇️ Add this import
#import <GoogleSignIn/GoogleSignIn.h>
  1. Modify your AppDelegate.swift file:
// …

@main
class AppDelegate: RCTAppDelegate {
  // …

  // ⬇️ Add this method
  override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    // Add any other URL handlers you're using (e.g. Facebook SDK)
    return ApplicationDelegate.shared.application(app, open: url, options: options) ||
           GIDSignIn.sharedInstance.handle(url)
  }

}

For AppDelegate written in Objective-C​

For AppDelegate written in Objective-C (the default prior to React Native 0.77), modify your AppDelegate.m file:

#import "AppDelegate.h"
#import <GoogleSignIn/GoogleSignIn.h> // ⬅️ add the header import

// …

@implementation AppDelegate

// …

// ⬇️ Add this method before file @end
- (BOOL)application:(UIApplication *)application openURL:(nonnull NSURL *)url options:(nonnull NSDictionary<NSString *,id> *)options {
  // Add any other URL handlers you're using (e.g. Facebook SDK)
  return [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url options:options] || [GIDSignIn.sharedInstance handleURL:url];
}

@end
