Xcode 15: Undefined symbols: Linker command failed with exit code 1 (use -v to see invocation)

upon upgrading to Xcode 15, my widget extension is causing this error:
Undefined symbols: Linker command failed with exit code 1 (use -v to see invocation)

When pressing the error, nothing happens. It doesn’t show me which symbols are undefined.

How should I fix this?

    Updating Firebase from 10.2 to 10.16 resolved the issue for me. The previously used BoringSSL-GRPC dependency, which caused the error for me, is now also gone.
