An attribute list cannot appear here firebase-ios-sdk, Xcode 15.0 Error

Question

I have updated my Xcode to 15.0 and now it's giving me this error:

ABSL_CONST_INIT extern "C" const int64_t kFIRFirestoreCacheSizeUnlimited =
            Settings::CacheSizeUnlimited;
   // An attribute list cannot appear here

I have gone through XCode 15.0 Release - firebase-ios-sdk bug: An attribute list cannot appear here issue on github but it does't provide support for swiftPackage manger.

Answer 1

update Firebase to v10 or change the line to

extern "C" const int64_t kFIRFirestoreCacheSizeUnlimited = Settings::CacheSizeUnlimited;

Answer 2

I was facing the same issue. I managed to fixed it by replacing this:

ABSL_CONST_INIT extern "C" const int64_t kFIRFirestoreCacheSizeUnlimited =
Settings::CacheSizeUnlimited; 

with this:

extern "C" const int64_t kFIRFirestoreCacheSizeUnlimited = Settings::CacheSizeUnlimited;
