@nidegen Could you please double check that you have FirebaseCore.framework version from 6.16.0 in your project? FIRHeartbeatInfo is a relatively new class but it was introduced in FirebaseCore before 6.14.0. The class was not used by Analytics or its dependencies before 6.15.0, that can explain why you don’t have the issue on 6.14.0.

yep tried at 6.17 and it works fine. Didn’t investigate what was the missing link

yep, my repro case does fork after 4819 fix (while also linking to sqlite3). I’ll doublecheck on the heartbeatinfo
