[Bug] Crash on macOS build when using any Firestore method call

[An-try]

Description

When using FirebaseFirestore.DefaultInstance.Collection().Listen(), the function works as expected in the Unity Editor. However, when I launch the built .app or run it through Xcode, the app crashes with 90% chance.

Expected Behavior: Listen() should work without crashing in the macOS build, just as it does within the Unity Editor.

Actual Behavior: The function call crashes the app during runtime when executed from the macOS .app build or when launched from Xcode.

I need assistance in identifying why this issue occurs only in the macOS build and not in the Unity Editor.

Reproducing the issue

1. Set Up Firestore in Unity.
2. Implement calling the Listen() method after Firebase is initialized.
3. Build the Unity project for macOS and run the .app or launch it from Xcode.

Behavior: After calling the StartListen() method, the log shows "id:..." as expected, but a crash occurs immediately afterward.

using UnityEngine;
using Firebase.Firestore;

public class FirestoreListener : MonoBehaviour
{
    private void Update()
    {
        if (Input.GetKeyUp(KeyCode.Space))
        {
            StartListen();
        }
    }

    private void StartListen()
    {
        Debug.Log("id: " + FirebaseFirestore.DefaultInstance.Collection("Development").Id);

        FirebaseFirestore.DefaultInstance.Collection("Development").Listen(snapshot =>
        {
            Debug.Log("snapshot");
        });
    }
}

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

Hi @An-try. What type of mac are you using? Namely, is it an Intel-based or ARM-based CPU? Also, please enable debug logging, reproduce, and attach updated logs. To enable debug logging, run FirebaseFirestore.LogLevel = LogLevel.Debug before doing anything with Firestore. If you are able to attach a zip file of a complete project that would also be helpful.

[An-try]

Hi @dconeybe.

I’m using a MacBook Pro with a 2.3 GHz Quad-Core Intel Core i5.

I have already enabled FirebaseApp.LogLevel = LogLevel.Debug, but enabling FirebaseFirestore.LogLevel = LogLevel.Debug didn’t change the logs. If needed, I can attach the logs below.

I will also prepare the Unity project and send it to you soon.

[dconeybe]

Thank you for the extra info. Could you try two things for me and let me know if the crash still occurs:

1. Delete the call to Listen()
2. Change the call to Listen() to GetSnapshotAsync()

[dconeybe]

@An-try Can you also try running https://github.com/firebase/quickstart-unity to see if you experience the same crash?

[dconeybe]

Oh, another thing: Are you calling FirebaseApp.CheckAndFixDependenciesAsync()? Make sure that you are doing this, as per the example in the quickstart: https://github.com/firebase/quickstart-unity/blob/3e667f84276c0d079eca89cc5e7e8764ae3c6358/firestore/testapp/Assets/Firebase/Sample/Firestore/UIHandler.cs#L64-L74

[An-try]

I am calling FirebaseApp.CheckAndFixDependenciesAsync(), and it works, as indicated by the log message Firebase initialized: Available that I sent previously.

I also tried the Firestore quickstart project and experienced the same issue.

I tried removing the Listen call and leaving only Debug.Log while retrieving the CollectionReference (FirebaseFirestore.DefaultInstance.Collection("Development")). For some reason, this is crashing the app too. Additionally, my other two Firestore methods also start crashing the app after that. And I experience this behaviour only in build, in Unity Editor everything fine. Something strange is happening and I will get back to this later and try to check all this again.

[An-try]

Hi @dconeybe

I created a completely new Firebase project and used the Firestore quickstart project, but I'm experiencing crashes on any button press in this quickstart project only in builds for macOS. I set everything up according to the guides, and everything works fine in the Unity Editor on macOS, but not in Xcode or the built .app.

I tested this on two different Mac devices:

MacBook Pro, 2.3 GHz Quad-Core Intel Core i5, macOS Sonoma 14.6.1 (23G93)
MacBook Pro, Apple M1 Pro, macOS Sonoma 14.6.1 (23G93)

I have no pending updates for my system or Xcode (v15.4).

I think we can close this issue and open a new one in the quickstart GitHub repository?

[An-try]

Also, I tested it with Unity 2022.3.20f1, Unity 2022.3.44f1, Unity 2023.2.19f1
And the newest Firebase package 12.2.1

[An-try]

Additionally, I tried creating a build (.app) directly from Unity without using Xcode, and the issue still persists.

[argzdev]

Hey @An-try, just wanted to add some insights here. I noticed that I was also able to replicate the crashing behavior on macOS platform with our Firebase Unity Quickstart for Firestore. However, I accidentally resolved this after adding my login for the keychain.

Steps I took:

1. Opened Firestore quickstart
2. Added Firebase Auth Sign In Anonymously (We've setup Firestore rules to restrict unauthorized transactions)
3. Build and Run for macOS, app crashes after any transaction with Firestore
4. Tried changing platform to iOS
5. Tested with iOS, app runs normal
6. Changed platform back and run macOS
7. The referenced pop up showed up to add login credential for keychain
8. The built macOS app no longer crashes.

I wonder if the issue in your case is also the same, though I'm not sure how to trigger or show the login credential for keychain manually. Let me know if this helps!

[An-try]

@argzdev Unfortunately, I cannot reproduce your solution. The keychain popup is not showing up after several attempts. I will look for a way to manually trigger this window somehow... or maybe another solusion
