Why am I getting this error involving `_kFIRLoggerInstanceID`?

I’m trying to upgrade our iOS app from Fabric Crashlytics 3.10.2 to Firebase Crashlytics 7.1.0. I’ve mostly gotten through the errors, and I’ve followed a few tutorials, and I’ve been googling around, but I can’t get rid of this error when linking:

Does anyone here know how to get past this?
