谷歌登录 iOS 崩溃？

Question

In an iOS project that uses Google Sign-In SDK (v5.0.2, added manually to the project, as well as GTM and Firebase), we have a crash that we could reproduce several times with a specific account on a specific device, when trying to sign in with a Google account.

The crash is:

** Assertion failure in +[UIAlertAction _actionWithTitle:descriptiveText:image:style:handler:shouldDismissHandler:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKitCore/UIKit-3901.4.5/UIAlertAction.m:42

The stack trace says the crash appears in

+[UIAlertAction actionWithTitle:style:handler:]
-[GIDEMMErrorHandler passcodeRequiredAlertWithCompletion:] + 556
-[GIDEMMErrorHandler handleErrorFromResponse:completion:]_block_invoke + 724

Poking with the debugger, it looks like UIAlertAction is passed a nil title, which causes an assertion failure.

The OS of the device is iOS 13.3.1.

I can't find an official way to report a bug in the Google Sign-In SDK, the Google issue tracker seems to be restricted to people with specific permissions, and they otherwise point to a forum that doesn't exist anymore, or to Stack Overflow...

The problem is that the resource bundle isn't being correctly linked in your project so the SDK gets a nil string for the action dialog which triggers the crash.

Until Google will gracefully fix it by providing a fallback string you can verify how you are linking the GoogleSignIn.bundle in your project
