Get the Google Sign-In SDK for iOS

The recommended way to include the Google Sign-In SDK in your iOS project is to use CocoaPods, but you can also download the SDK and manually configure your project to use it.

Download the Google Sign-In SDK

Version 5.0.0 of the Google Sign-in SDK for iOS introduced some API changes incompatible with prior versions. See the quick migration guide for upgrade instructions.

Add the SDK your Xcode project

  1. Extract the SDK archive you downloaded and copy the following files to your Xcode project:

    • GoogleSignIn.bundle
    • GoogleSignIn.framework
    • GoogleSignInDependencies.framework

  2. Add GoogleSignIn.bundle to your Xcode project's Copy Bundle Resources build phase.

Link the following frameworks to your Xcode project:

  • LocalAuthentication.framework
  • SafariServices.framework
  • AuthenticationServices.framework
  • SystemConfiguration.framework

Add the ObjC linker flag to the app target's build settings:

  • Other Linker Flags: $(OTHER_LDFLAGS) -ObjC

Get an OAuth client ID

If you haven't already created an OAuth client ID, click the button below to do so.

Create an OAuth client ID

After you create the OAuth client ID, take note of the client ID string, which you will need to configure Google Sign-in in your app. You can optionally download the configuration file, which contains your client ID and other configuration data, for future reference.

If you already created an OAuth client ID, you can find your existing OAuth information by clicking the button below.

Add a URL scheme to your project

Google Sign-in requires a custom URL Scheme to be added to your project. To add the custom scheme:

  1. Open your project configuration: double-click the project name in the left tree view. Select your app from the TARGETS section, then select the Info tab, and expand the URL Types section.

  2. Click the + button, and add your reversed client ID as a URL scheme.

    The reversed client ID is your client ID with the order of the dot-delimited fields reversed. For example: 

    com.googleusercontent.apps.1234567890-abcdefg

When completed, your config should look something similar to the following (but with your application-specific values):

Next steps

Now that you've downloaded the project dependencies and configured your Xcode project, you can follow the guide to add Google Sign-In to your iOS app.
