Failed to handle openURL

[comtaler]

I am using Firebase for my game and we also integrated Facebook. However, after I connect to facebook on iOS, it stays on the webview and does not return back to the game. I got a hint from (http://stackoverflow.com/questions/35100809/unity-facebook-sdk-ios-9-2-not-returning-to-app) and finally figured that it is Firebase plugin that failed to handle openURL. After removing Firebase from the project, facebook login works fine.

Which Firebase component did you remove which resulted in this working? Any chance it was FirebaseMessaging? If so I think we have a fix in the pipeline for this.

I removed all Firebase plugins (messaging, analytics, and dynamic links)

[stewartmiles]

If you just add Analytics do things start working?

I think this issue is associated with the way we were swizzling methods on the app delegate in Messaging and Invites plugins. We have a fix which will be released soon.

[stewartmiles]

I'm pleased to announce that we released:

• Firebase C++ SDK 2.1.0 (release notes here, download here)
• Firebase Unity SDK 1.1.0 (release notes here, download here)

I believe this should resolve your issue. If not, please let us know and we'll take a look.

Cheers,
Stewart

After updating to the latest SDK, the problem is still there.

[stewartmiles]

Are you able to reproduce this issue with one of our samples? For example, if you add the Facebook plugin to the Analytics sample does it fail in the same way?

[comtaler]

Here is what we found. The plugin works fine with the sample project but failed with out project. The difference is that in our project, after importing the sdk, it throws StackOverflowException as another bug I reported here (#27). I think that prevents Unity from patching Info.plist file because I don't find anything being added to "URL Types" there. Once the other issue is fixed, I can verify whether this one is fixed as well.

I think I'm experiencing the same issue. Found an interesting post on Facebook's bug reports that might be related.

Also, I confirmed on 1.0 that the values from both Facebook and Firebase are added to the URL types just fine:

Here's a video that shows the error with Facebook: http://youtu.be/mqCS8phA_NE

Does Firebase's libraries edit the openUrl method at all? Maybe through invites?

@comtaler how did you guys go about fixing this?

[PimDeWitte]

Edit:

Fixed it by removing Firebase Invites @stewartmiles

Also @comtaler if you're using 5.5 don't forget to implement this:
Just drag it in Plugins/iOS
