The forum has an old thread that reports problems with the Firebase frameworks included in the latest Buildserver. The error message was "The signature of “nanopb.xcframework” cannot be verified. note: A sealed resource is missing or invalid".
The thread alluded to a rather involved process which involved downloading the firebase library directly from google and overwrite the files that came with the Buildserver.
A suggestion was made to publish a corrected buildserver. Erel commented "I guess that this issue will eventually be resolved."
Has it been resolved or is the only recourse to overwrite libraries in Buildserver?
