There's not enough information in this issue to debug. Please fill out the issue template and include the version of Firebase Auth, the code you're using to integrate Firebase, and any errors in console, then re-open this issue.

Kindly reopen this issue as it not has been solved

[vinayakpal]

is there any progress to solve this issue. please help urgently

Can you try using the flag FirebaseAppDelegateProxyEnabled=NO in the Info.plist and see if it solves the problem (Please follow the instruction in FIRAnalytics+AppDelegate.h if you decide to do so). If it is still not working, can you try unlink one of Analytics or Auth from your app? We would like to determine which Firebase SDK is causing the issue. Thanks

@vinayakpal there are a number of issues with your implementation, including issues not specifically related to Firebase.

Please move your question to StackOverflow and make sure to include any relevant error messages when running your project.

@morganchen12 I recently found that i forgot to enable keychain sharing in App Capability section. But later on I enable that but still no progress found in login. can you please help this regarding this keychain issue.

We are facing the same issue, Just update the POD file and enabled key chain sharing also. Google sign in not coming back to the App. And it works well in iOS 11 but not in iOS 10.2.1. Any update ?

FWIW we appear to have just run into this issue when upgrading our cocoapods.

We had been using Facebook iOS SDK 4.34, then upgraded to 4.39 and a little bit later realized that we got hit by the "unknown error building URL" issue (https://github.com/facebook/facebook-swift-sdk/issues/298). We then upgraded to 4.42, which fixed Facebook login when using Safari, but not when using the Facebook app.

It appears that FirebaseAppDelegateProxyEnabled=NO fixed this issue.

Did something change regarding app delegate proxies between 4.34 and 4.42?

Was this swizzling-the-app-delegate-methods-by-default decision made in an effort to make things easier for developers? If so, this strikes me as a good example of what Rich Hickey was talking about with his "simple vs easy" concept: https://www.youtube.com/watch?v=rI8tNMsozo0. This swizzling has made things easier, but not simpler, which made it much more difficult for us to debug this issue (i.e., in terms of developer time it would have been much less expensive for us if swizzling weren't available and we were forced to forward the app delegate calls manually).

[morganchen12]

Hey all, sorry for the slow response here. The goal of the FirebaseAppDelegateProxyEnabled flag was to allow developers to choose between easy or simple, but it's woefully missing from our docs. I'll take a look at fixing that soon.

In the meantime, is this still an issue in Firebase 6+ and Facebook SDK 5+?
