Step 2: Describe the problem

I get the following error when uploading to App Store connect.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Sorry about the trouble and thanks for the report.

Please share the Xcode version being used as well.

[paulb777]

Thanks. This looks like an issue between Swift Package Manager and the App Store. SPM should not generate symbols that the App Store does not allow. We may need to follow up on Apple on this one.

Another option may be to remove the underscores from the GoogleUtilities package.

Strange that https://github.com/google/GoogleSignIn-iOS/issues/124 was first reported on April 21st, but today is only report since. Based on those stats, it seems like there may be something particular about the specific project configuration.

Does updating to Xcode 13.4.1 make a difference?

[yutaabe200]

I'm having trouble with the exact same thing with Xcode 13.4.1...

@paulb777 Hopefully I can reproduce the issue for a demo app soon so we can identify why this only occurs for some apps, but in the mean time it would be great if the change to remove underscores could be made on your side too, given Apple says underscores are disallowed in that thread and in the rejection reason.

[jackgmarch]

@paulb777 We're linking Firebase Analytics/Crashlytics to a framework target, similar to the person in this thread https://bytemeta.vip/index.php/repo/google/GoogleSignIn-iOS/issues/124 who had the issue. Fixing this on our end would require a lot of code changes, and I'm pretty sure it's a valid setup, so unfortunately probably our only realistic way out is for the underscores to be removed if this is the cause.

This issue only started occurring for us recently as we just started using Firebase as a dependency via SPM, before we used Carthage.

[paulb777]

Yep linking into a dynamic framework could explain the issue. Would you create a reproducible example and file an issue to https://github.com/apple/swift/issues/new?assignees=&labels=bug&template=bug_report.md&title= as requested at https://developer.apple.com/forums/thread/704934.

We'd like to hear a statement from Apple before making a breaking change in the Firebase support libraries.

[lugearma]

I finally was able to solve this, I was linking Firebase into a dynamic framework so I removed the framework and linked it into my app target directly.

[paulb777]

Marking for Firebase 10 to consider a GoogleUtilities breaking change release at the same time.

[paulb777]

Punting to Firebase 11 since we no longer plan to do a GoogleUtilities breaking change in Firebase 10. GoogleUtilities will need to continue to support iOS 10 past the release of Firebase 10.

I am getting this error now too after switching to SPM. Is there a work around? I have multiple frameworks and app linking to Firebase, so I need to use a dynamic library.

[paulb777]

Even if we updated GoogleUtilities Package.swift to work around the SPM bug, there would still be the issue that FirebaseAnalytics is distributed as a binary static framework.

[jasonbobier]

This is actually ok for me atm because FirebaseAnalytics is only being used by a single framework on our side. The issue is that other frameworks use other Firebase components (Installations, RemoteConfig, Messaging, DynamicLinks) and I assume that multiple of those are pulling in GoogleUtilities causing it to become dynamic.

Hi everyone, we identified a fix in GoogleUtilities that should prevent this issue. We will release it in a SwiftPM-only GoogleUtilities 7.9.0 release sometime next week. I will update this bug when that happens. Thanks for your patience!

[ncooke3]

Quick update– GoogleUtilities 7.9.0 is released and has the fix for this issue. Please reach out if it gives you any trouble.
