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

@dsert1 Thank you for reporting this issue. However, I am not seeing the same issue when I compile using Xcode 15. If possible, could you do the following:

1. Try to compile the "quickstart" Firestore application using your Xcode 15 setup. To do this, clone the https://github.com/firebase/quickstart-ios repository and attempt to compile and build the application in the "firestore" subidrectory.
2. Provide a screenshot or full log of the compilation error.
3. Try to figure out which version of the Firebase iOS SDK that you are using (e.g. the latest at the time of writing is 10.15.0).

Thank you.

@dsert1 I had the same issue. I think you may be operating on Firebase 9.6.0 SDK version.

I fixed the issue by going into my Project - Package Dependencies.

I changed the range by changing the drop down from "Update to Next Major Version" to "Range of Versions" then changing it from 9.0.0 < 10.0.0 to 10.0.0 < 11.0.0

Then changed the drop down back to 'Update to Next Major Version'. Once that set in, the packages updated and my project ran fine.

Hope that helps.

I got the same issue as well. Here is the details of my side:
I'm using SPM - Firebase 9.6.0
Error Line:
ABSL_CONST_INIT extern "C" const int64_t kFIRFirestoreCacheSizeUnlimited = Settings::CacheSizeUnlimited;
Error: An attribute list cannot appear here
Error file path : Firebase -> Firestore -> API -> FIRFirestoreSettings / Line - 33

For anyone experiencing this issue, please attempt to reproduce in the latest version, which is 10.15.0 at the time of writing. If this is fixed in the latest version then the "fix" is to upgrade. Otherwise, we will fix it in the next version. So either way, an upgrade will be needed in order to get the fix. Thanks!

any update for this bug.

[dconeybe]

@Resource-2 What version of the Firebase SDK are you using? It looks like this problem only occurs with old versions of the SDK. Does the problem go away when you upgrade to the latest version, which is 10.15.0 (at the time of writing)?

@rharshaw solution worked for me.

[dconeybe]

I am going to close this issue since there have been several reports that upgrading to the latest version of the Firebase SDK has fixed the problem. If anyone experiences this issue with the latest version, which is 10.15.0 at the time of writing, or newer, then please leave a comment or open a new issue and we will investigate.
