'Google Sign in fails on iOS 13 GM

My app has a Sign in with Google button. When I try to sign in on iOS 13.0 GM GIDSignInDelegate didSignInForUser:WithError: returns this error:

Error Domain=com.google.GIDSignIn Code=-1 "The operation couldn’t be completed. (org.openid.appauth.general error -3.)"

I have no clue how to fix this issue. I'm using Google Sign In 5.0.0 as part of Firebase 6.8.1.

I figured it out! The AppAuth-iOS, which is a open-source dependency of GoogleSignIn SDK, has been updated from 1.1.0 to 1.2.0 in August, including this iOS 13 support. So you need to run pod update GoogleSignIn to update the AppAuth to 1.2.0. The GoogleSignIn SDK itself hasn't been updated since 5.0.0, so that got me confused.

Following is the solution for successfully having the login view. Call the signin method after the ViewController's view is appeared, it will not be dismissed programatically. I have just implemented in IOS 13 and it works fine.

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    GIDSignIn.sharedInstance()?.delegate = self
    GIDSignIn.sharedInstance()?.presentingViewController = self
    GIDSignIn.sharedInstance()?.scopes = [kGTLRAuthScopeDrive]
    GIDSignIn.sharedInstance()?.prepareForInterfaceBuilder()
    GIDSignIn.sharedInstance()?.signIn()
}

I downloaded the Firebase 6.9.0 SDK zip and experienced this same issue. The README indicated that the bundled version of AppAuth was 1.2.0. I was able to resolve it by updating AppAuth to the master version.

Specifically, I removed the AppAuth framework included with Firebase, and instead build AppAuth using Carthage.

For future reference when other users find this question:

Google fixed this issue in GoogleSignIn v5.0.1. When updating your app to iOS 13, you'll likely have to update the GoogleSignIn SDK as well.

Solution 5:^[5]

If you are using Firebase 6.9.0 from Carthage, add github "openid/AppAuth-iOS" "master" to your Cartfile below any Firebase entries.

Sorry if wrong.

I thought this error would happen without targeting.

Support not only from 13, but also from 10.

Solution, but don't keep your pod version up to date.

4.4.0.

pod 'GoogleSignIn', '4.4.0'

It was all right for this version.

I anticipated the error. Less than

The new version may use some code generated by xcode11.3, So new is OK, existing one may stop processing at 13
