We have the same in Unity 2022.3.50f. Downgraded back to Firebase 12.2.1.

Also seeing the same issue with an older version of Unity, so it's probably not a Unity version issue. We had to downgrade to 12.1.0 due to some issues with Sign In with Apple occurring in 12.2 that we were hoping would be fixed by 12.4 (but can't check due to this).

Anbody found any solution to this problem? Downgrading Firebase version worked for anyone? If yes, which version is more stable?

@JeongDongKyun

You can try version 12.0.0

Hey folks, thanks for bringing this up to our attention. While we investigate this further, could you help me with the steps to reproduce this behavior?

What I did was the following, however I didn't encounter any issues:

  1. Create a new project in Unity
  2. Use Assets > Import Package > Custom Package...
  3. Add version 12.4.0 of Firebase Analytics, Crashlytics, Messaging, RemoteConfig
  4. Build project with iOS platform
  5. Open in Xcode then select Product > Archive

Am I missing anything? Does this issue only happen during archiving or does it also happen when building? I'm also testing with Unity 6000.0.23f1 if that makes any difference.

Having same errors with Unity 6000.0.27f1 and Xcode 16.1.
Currently latest working version is 12.3.0

Hi all,

While we haven't been able to reproduce the error ourselves, using disassembly tools I have spotted some additional symbols that are present in the C# libraries about SWIGStringWithLengthHelper, which seems to be the root cause of the issue. While I try to determine a proper fix for this, unfortunately the best idea I have is to use 12.3.0.

Sorry for the inconvenience.

same problem with Xcode 16.1. v12.3.0 works with Xcode 16.1

Hey @R1NoB, you may find the different versions here. You may also find each Firebase product's different versions .unitypackage in the link.

Alright, this should be resolved with the latest release https://github.com/firebase/firebase-unity-sdk/releases/tag/v12.4.1

I wasn't able to reproduce this error myself, but I confirmed with disassembly tools that the SWIGStringWithLengthHelper logic has been removed from the libraries, so hopefully it'll all be good to go.

Thanks for bringing this to our attention.

And thanks for your interest.

As soon as I've seen regarding release I've tried to rebuild again.. and good news it's working.

Thanks again..
