Google Sign-In SDK v7.0.0+

To migrate your app from a version of the Google Sign-In SDK prior to v7.0.0, make the following changes:

• Set your OAuth client configuration in your application's Info.plist file. You can continue to set it at runtime (using a GIDConfiguration ) object, but this is no longer recommended. See the get started guide for examples and more details.

  Info.plist key	Description
  GIDClientID	OAuth client ID
  GIDServerClientID	Server OAuth client ID for backend authentication
  GIDHostedDomain	Google Workspace domain
  GIDOpenIDRealm	OpenID realm

• The addScopes: method has been moved to GIDGoogleUser. Instead of requesting additional authorization scopes from GIDSignIn, you should now request them from GIDGoogleUser after authentication has completed.

• If you are setting serverClientID to enable server-side API access for your app , serverAuthCode will now be returned with GIDSignInResult in your completion.

• Properties from GIDAuthentication have moved into GIDGoogleUser .

• Update method calls:

v6.2.x	v7.0.0+
GIDSignIn signInWithConfiguration:presentingViewController:callback:	GIDSignIn signInWithPresentingViewController:completion:
GIDSignIn restorePreviousSignInWithCallback:	GIDSignIn restorePreviousSignInWithCompletion:
GIDSignIn disconnectWithCallback:	GIDSignIn disconnectWithCompletion:
GIDAuthentication doWithFreshTokens:	GIDGoogleUser refreshTokensIfNeededWithCompletion:
GIDSignIn addScopes:presentingViewController:callback:	GIDGoogleUser addScopes:presentingViewController:completion:

Google Sign-In SDK v6.0.0

To migrate your app from a version of the Google Sign-In SDK prior to v6.0.0, make the following changes:

• Update all [GIDSignIn sharedInstance] calls to GIDSignIn.sharedInstance property accesses.

• Move all client configuration (client IDs, etc.) to a GIDConfiguration object.

• Update calls to removed methods to their new equivalents:

  v5.x.x	v6.0.0
  signIn	signInWithConfiguration:presentingViewController:callback:
  restorePreviousSignIn	restorePreviousSignInWithCallback:
  disconnect	disconnectWithCallback:
  getTokensWithHandler:	doWithFreshTokens:
  refreshTokensWithHandler:	doWithFreshTokens:

• Remove all references to the GIDSignInDelegate protocol and its methods.

  • Move the logic from signIn:didSignInForUser:withError: to the callback block of signInWithConfiguration:presentingViewController:callback: .

  • Move the logic from signIn:didDisconnectWithUser:withError: to the callback block of disconnectWithCallback: .

• Manually connect GIDSignInButton to a method that calls signInWithConfiguration:presentingViewController:callback: using an IBAction or similar.
