Facebook and Google singin not working on iOS 9.x and 10.x FirebaseUI

[nole87]

Step 1: Are you in the right place?

Yes, firebase supports direct me here

Step 2: Describe your environment

Swift 4.0
iOS 9.x or 10.x
newest Firebase and FirebaseUI via pods

Step 3: Describe the problem:

In my last version of app everything works fine, all was configured for all auth providers and with FirebaseUI. I now prepare new version of my app and only for iOS 9.x and iOS 10.x Facebook and Google sing in doesn't work anymore. For 11.x and 12.x it works! I get this error: -canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)" For Google I don't get any error

Can you share a project that reproduces this issue?

The OSStatus error occurs when the facebook app isn't installed, and is safe to ignore (the OAuth flow will be completed in a Safari window instead).

I will try later or for weekend to share temp project to demonstrate bug.

I will attach project as soon as possible because I must remove lot of project!!! :)

Here is link for project: https://drive.google.com/file/d/16tJZQL4iEo_q9eWjG22sQxGDJy6ITfUh/view?usp=sharing

Please, try iOS 9 and 10 than 11 and 12. On 9 and 10 it doesn't work and on 11 and 12 it works :)

Thanks!

I wasn't able to reproduce the error on iOS 10 (haven't tried iOS 9). Google sign in works as expected. What error are you getting?

[nole87]

-canOpenURL: failed for URL: "fbauth2:/" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"

On iPhone 7 simulator iOS 10.3.1 I get above error for facebook. For google I don't get error but it doesn't sing in. Also this happen for iOS 9. I try on real device iPhone 6S, iOS 10.x same bug ...

[morganchen12]

Your web flow looks like it's signed in. What happens when you press Done in the upper left?

[nole87]

It shows this:

In my opinion it's not good, it should close automaticly. Strange for me because it was working, now only on iOS 9 and 10 it doesn't. For iOS 9 and 10 I disable facebook and google provider but I don't know how much of users are on these platform. Probably not to much, so it's ok if we don't resolve :)

[morganchen12]

Hm, seems like a bug (the dialogue should dismiss on a successful login). Can you try updating to the latest version of Firebase? I'll keep this issue open in case any one else has the same issue.

[nole87]

I did, I use pods and always before update I use pod update ...

What about facebook provider, in my opinion it's more important on iOS than google ...

The same thing happening to me. Google sign-in on iOS 10 doesn't work, it shows "one moment please" then goes to google site as same as the screenshots above. iOS 11+ works well. I'm sorry I am not allowed to share my project.

I found what causes this issue. In my case, handling the URL wasn't set up correctly.

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options {
  NSString *sourceApplication = options[UIApplicationOpenURLOptionsSourceApplicationKey];
  return [[FUIAuth defaultAuthUI] handleOpenURL:url sourceApplication:sourceApplication];
}
