[Bug] FirebaseCore_Privacy.bundle not found about firebase-unity-sdk

[andymillermz]

Hey folks - we figured out the issue here.

Somehow these recent bundle changes seems to now break with the xcode build flags we set.

We were using CONFIGURATION_BUILD_DIR to set the directory where all build steps would happen - this includes all those xcode build and intermediate steps that happen in the DerivedData location.

Unsure when that changed but it seems that the flag is no longer properly respected when building an xcode workspace. It still behaves the same when building an xcode project file alone.

When running xcodebuild with -derivedDataPath and -archivePath flags we can now get full builds along with keeping all build files and data under our build directory.

Appreciate the help 👍

Great that you were able to track down the issue, thanks for following up. Searching for issues with Cocoapods and CONFIGURATION_BUILD_DIR I do see a few issues, though naturally all different enough to make it hard to find without already knowing that is the problem. We'll aim to keep an eye out for that field in the future for similar types of issues.

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

Hi @Nathanael-MZ

Unfortunately we haven't been able to reproduce this on our end. What version of XCode are you using? I see the error that you posted suggests running pod install, have you tried doing so from the directory that you created the xcode project in? Finally, if you can share your Podfile.lock, that would help indicate what dependencies are being included in your project.

[Nathanael-MZ]

We are running XCode 15.0.1. The FirebaseCoreInternal_Privacy.bundle is in the build folder but we still get the file not found error.

Thanks. Discussing this with the Firebase iOS team, the issue is likely caused by the recent changes on the Apple side around Privacy Manifests, info here: https://developer.apple.com/support/third-party-SDK-requirements The Firebase iOS SDK added the privacy manifests in 10.22.0, which for the Unity SDK was the recent 11.8.0 release. It could be that XCode is looking for the privacy manifest, and failing to find it because you have 10.11.0 of the FirebaseCore pod (though I didn't think they were enforcing this until May), so one potential fix would be to update the versions you are using.

Another possibility, in the Podfile.lock it is getting a couple of Firebase internal pods at 10.23.0, instead of 10.11.0. Normally, this shouldn't cause issues, but possibly it is because of the privacy manifest changes. So what you can try is pinning FirebaseCoreInternal and FirebaseInstallations at 10.11.0 as well. You can do this by either editing the Podfile that is generated by the Unity build, or in the Unity project, edit your Assets/Firebase/Editor/AppDependencies.xml, and add those pods with those version numbers, which will cause the Podfile to be generated with them. If you are using the Firebase SDK through a Unity package such that you don't have that file, you can add one, copying the format from the one that should be in your packages, and then add the lines.

Hi @Nathanael-MZ, could you confirm that you are opening the .xcworkspace file rather than the .xcodeproj file?

[Nathanael-MZ]

Hi @Nathanael-MZ, could you confirm that you are opening the .xcworkspace file rather than the .xcodeproj file?

Yes, we are using the .xcodeproj file

[ncooke3]

@Nathanael-MZ, try closing the window with the .xcodeproj and re-opening the .xcworkspace. Then, build. Running pod install generates an .xcworkspace, and that should be used to develop rather than the .xcodeproj.

[Nathanael-MZ]

Sorry, I was wrong. We do the pod install, then build with the xcworkspace.

[ncooke3]

No worries. That's interesting. I was able to reproduce the issue when building the .xcodeproj, but not when when building .xcworkspace. There's definitely something else going on then. Could you share your Podfile? Feel free to redact target names and what not. I'd like to see the structure and use it to attempt to reproduce in a simple app.

[supergardener]

@a-maurice Thank you for the detailed information. Considering the recent changes in Apple's Privacy Manifests, it seems plausible that the issues stem from compatibility with older versions of Firebase iOS SDK. Could you please confirm if there have been any recent updates to the Firebase Unity SDK that might address these concerns? We're eager to resolve the issue and ensure compatibility with the latest requirements from Apple.

[Nathanael-MZ]

We are using the latest Firebase Unity SDK 11.8 and we tried upgrading to XCode 15.3.

I've tried reproducing this with the same Unity version, and using older Cocoapods to force a mismatch of the versions, and still haven't had any luck on my end. My best guess is that something is preventing the pods from being put into the working directory, but no idea what that might be.
