Enables iOS apps to sign in with Google with additional permissions

Google Sign-In for iOS

Get users into your apps quickly and securely, using a registration system they already use and trust—their Google account.

Visit our developer site for integration instructions, documentation, support information, and terms of service.

Getting Started

Try either the Objective-C or Swift sample app. For example, to demo the Objective-C sample project, you have three options:

1. Using CocoaPods's try method:

pod try GoogleSignIn

Note, this will default to providing you with the Objective-C sample app.

2. Using CocoaPod's install method:

git clone https://github.com/google/GoogleSignIn-iOS
cd GoogleSignIn-iOS/Samples/ObjC/SignInSample/
pod install
open SignInSampleForPod.xcworkspace

3. Using Swift Package Manager:

git clone https://github.com/google/GoogleSignIn-iOS
open GoogleSignIn-iOS/Samples/ObjC/SignInSample/SignInSample.xcodeproj

If you would like to see a Swift example, take a look at Samples/Swift/DaysUntilBirthday.

• Add Google Sign-In to your own app by following our getting started guides.
• Take a look at the API reference.

Mac Catalyst

Google Sign-In supports apps built for Mac Catalyst. In order for your Mac Catalyst app to access the keychain on macOS you will need to enable the Keychain Sharing capability. No keychain groups need to be added.
