[REQUIRED] Please fill in the following fields:

  • Unity editor version: 2021.3.32f1
  • Firebase Unity SDK version: 11.6.0
  • Source you installed the SDK: Unity package manager via tgz
  • Problematic Firebase Component: Realtime database
  • Other Firebase Components in use: None
  • Additional SDKs you are using: None
  • Platform you are using the Unity editor on: MacOS 14.0 with xCode version 15.0.1
  • Platform you are targeting: iPhone 6 iOS 12.5.7
  • Scripting Runtime: IL2CPP

[REQUIRED] Please describe the issue here:

When trying to register for a value changed in the realtime database, the app crashes on the iPhone 6. This only occurs on the iPhone 6 and not on later iPhones. When the app crashes, xcode outputs a cryptic message:

0x100aa4000: .long 0xfeedfacf ; unknown opcode

Steps to reproduce:

  • Install firebase through the package manager
  • Add GoogleService-Info to the project
  • Add the script below (see following section)
  • Build the project through xCode
  • Notice the crash on iPhone 6.
  • Notice that the crash does not occur on more 'modern' iPhones, which my collegues have

I was also able to reproduce this issue in the samples project.

I also tried downgrading the firebase SDK to 10.6.0 and the issue also occured here.

Relevant Code:

public void ReadSomeValueChange()
    {
        string dataBaseUrl = "https://<yourfirebaseurl>.firebasedatabase.app/";
        Debug.Log("Before getting instance");
        var dataBase = FirebaseDatabase.GetInstance(dataBaseUrl);
        Debug.Log("Before getting reference");
        var somePath = dataBase.GetReference("/test");
        Debug.Log("Before registering to value changed");
        somePath.ValueChanged  = HandleValueChanged; // APP CRASHES HERE
    }

    private void HandleValueChanged(object sender, ValueChangedEventArgs args)
    {
        // app does not reach this line
        Debug.Log("Value changed");
    }

We're also experiencing similar problems with iOS 12.5.5 and iOS 12.5.7, using Firebase 11.5.

We saw two separate crashes, one from realtime database:
