# 10.1.0 - DEPRECATE COCOAPODS DISTRIBUTION. This is the last release published to CocoaPods, which becomes read-only on December 2, 2026 - migrate to Swift Package Manager using [MIGRATING_FROM_COCOAPODS.md](https://github.com/google/GoogleSignIn-iOS/blob/main/MIGRATING_FROM_COCOAPODS.md). ([#656](https://github.com/google/GoogleSignIn-iOS/pull/656)) - Support AppCheckCore 12.x, so apps using Swift Package Manager can now upgrade to Firebase 13 (the podspec also accepts AppCheckCore 11.x or 12.x). With AppCheckCore 11.x, a custom App Check provider that returns neither a token nor an error now counts as success, and a failed App Check preparation is no longer reported as successful. ([#626](https://github.com/google/GoogleSignIn-iOS/pull/626)) - Fix concurrency issues in `GIDGoogleUser`: - Key-value observers of `accessToken`, `refreshToken`, `idToken` and `profile` are now notified whenever any of them changes, so they never see a half-updated user (`profile` previously sent no notifications). `configuration` is now fixed when the user is created, instead of possibly reflecting a later token update. ([#651](https://github.com/google/GoogleSignIn-iOS/pull/651)) - Key-value observers are now notified while `GIDGoogleUser` holds its internal lock. Calling back into the same user is fine, but an observer must not synchronously wait (e.g. with `dispatch_sync`) on another thread that is updating that user. ([#652](https://github.com/google/GoogleSignIn-iOS/pull/652)) - `grantedScopes` and `accessToken` no longer revert to their pre-add-scopes values when a token refresh was in flight while scopes were added. ([#653](https://github.com/google/GoogleSignIn-iOS/pull/653)) - Readers no longer see a mix of old and new tokens during a concurrent update. ([#645](https://github.com/google/GoogleSignIn-iOS/pull/645)) - Fix a custom `nonce` and requested `claims` being dropped when a sign-in is continued after a Device Policy app restart. ([#637](https://github.com/google/GoogleSignIn-iOS/pull/637)) - Fix EMM remediation dialogs being suppressed for the rest of the app's lifetime after an error arrived with no key window, and EMM errors sometimes being reported as `kGIDSignInErrorCodeUnknown` or the underlying OAuth error instead of `kGIDSignInErrorCodeEMM`. ([#642](https://github.com/google/GoogleSignIn-iOS/pull/642)) - Fix a crash when a server error response carries a non-string value under its `error` key.

Projects that must keep supporting earlier OS versions should stay on GoogleSignIn 9.2.0. ([#628](https://github.com/google/GoogleSignIn-iOS/pull/628)) - Add `GIDSignIn.wrapperIdentifier` so SDKs that embed Google Sign-In can self-identify in Google's diagnostic logs via a new `gidwrapper` parameter. It is opt-in and pre-existing behavior is unchanged.

Please note that it is intended that neither `signIn:presentViewController:` nor `signIn:dismissViewController:` is called on iOS 11 because SFAuthenticationSession is not presented by the app's view controller. # 4.1.0 - Uses SFAuthenticationSession on iOS 11. # 4.0.2 - No longer depends on GoogleAppUtilities. # 4.0.1 - Switches to open source pod dependencies. - Appearance of sign-in button no longer depends on requested scopes. # 4.0.0 - GoogleSignIn pod now takes form of a static framework.
