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.
