Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)? What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur? This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will likely receive a faster response on your issue.

Relevant Code:

// TODO(you): code here to reproduce the problem

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

[paulinon]

Hi @aslmtrt,

Does updating the SDK to its latest version (11.5.0 as of writing) make any difference? If not, could you share your Podfile along with the steps to reproduce the issue so we can identify what's causing this to happen?

[aslmtrt]

Hi @paulinon Thank you for your repply. I updated to the latest version but the problem still persists.

[paulinon]

Hi @aslmtrt,

Could you provide a minimal, reproducible example of your implementation along with detailed steps to replicate the issue so we can identify what's causing this to happen?

We are experiencing the same crash after an update of Unity from 2021.3.12f -> 2021.3.28f With this update we also updates Firebase from 9.0.0 -> 11.2.0

Unfortunately we have only been able to see this in Crashlytics for now and don't have a reproduction case. It's happening almost exclusively on iOS/iPadOS 12.

Hey @aslmtrt. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

Hi, I have the same crashes on iOS 12.5 devices on my last game update. Tested with 11.4.0, 11.6.0 and the problems is the same. Currently using Unity 2021.3.31f1 (LTS), MacOS 14.0, xCode 15.0.1.

Here is a small repro project, just add your packages as listed in the Packages/manifest.json otherwise the archive is too big to upload here. I also removed the google-service... file.

As I tested: 1 - Open the project. 2 - make sure to target iOS platform. 3 - build and run targeting xCode 15. 4 - run on an iPhone 6 device (iOS 12.5.7) 5 - on the launched app, click on the button START. 6 - see the crash happening. FirebaseCrashIOS12.zip

Hi, Just a follow up to prevent your bot to close the issue...

As your bot said it's been more than 5 weekdays now and I'm still waiting for a response.

I think we gives you all you need to find and fix the bug, this bug seems pretty simple to reproduce and I gives you a sample project to reproduce it as asked by @paulinon.

I'm still available to answer any question you could have.

Thanks.

[aslmtrt]

We updated Firebase libraries. We downgraded the Unity version. We tried similar different steps, nothing changed. We upgraded the Unity version again and got a new build.

In this build, we turned off analytics and firebase usage for OS 12. (FirebaseAnalytics.LogEvent)

Crashes related to Analytics and Firebase continued, but the number of crashes decreased. Crashes only occurred on iPhone 6 OS 12.

As far as I understand, the problem occurs when sending analytical events for iPhone OS 12.

I'm using Unity 2021.3.21f1, Firebase 10.7.0, xcode 15.1 and I'm getting the same crash on iPhone SE / iOS 13.

There seems to be no problem when using xcode 14.x version.

However, since I need to use xcode 15, this problem should be resolved. Thanks

[binouze]

@a-maurice @cynthiajoan @sunmou99 @chkuang-g, anyone could take a look at this please ?

[baba-s]

I had encountered a similar problem, but was able to resolve the issue with the responses on the following pages. https://baba-s.hatenablog.com/entry/2023/11/27/091420

[Ceikry]

We were able to confirm with 100% certainty that building the app with Xcode 14 instead of Xcode 15 resolved this crash for us.

[lagoonbbbo]

@baba-s Thanks, it seems to fix the issue.

Xcode 15.1 was fixed this issue. Check more information here: https://developer.apple.com/documentation/xcode-release-notes/xcode-15_1-release-notes#Linking

and here is this bug on XCode 15.0 : https://developer.apple.com/documentation/xcode-release-notes/xcode-15-release-notes#Linking
