iOS Widget - GIDSignIn Code=-4 (kGIDSignInErrorCodeHasNoAuthInKeychain)

[kevin-hv]

Description of the bug I have an application & a widget for iOS. I have a user logged in to my application via the GIDSIgnIn iOS SDK. When I try to use the GIDSignIn.sharedInstance.restorePreviousSignIn() function from my widget to restore the session in order to call the google APIs to fetch data which I need to update the Widget's UI, the function throws the GIDSignIn Code=-4 (kGIDSignInErrorCodeHasNoAuthInKeychain) error.

To Reproduce Steps to reproduce the behavior:

1. Have an iOS app
2. Have an iOS widget for the app
3. Sign in in your iOS app with the GIDSignIn SDK
4. Try to restore the sign in session in the iOS widget inside the AppIntentTimelineProvider's timeline(for configuration: ConfigurationAppIntent, in context: Context) async -> Timeline function

Expected behavior

• The GIDSignIn SDK to restore the session & user data to be able to fetch data from Google's APIs

Environment

• Device: iPhone 15
• OS: iOS 17.2

If anybody comes across this problem, I have seen that the keychain name GIDSignIn uses is auth, if you add this to keychain sharing on BOTH your app & your widget, it will work ^^.
