Hey @Nick! Daniel from Customer Support Engineering here 🔧Thanks for flagging this with us. Can you please try this on the newest version of the SDK to see if it still persists? To be transparent, there are some Xcode warnings that are thrown that we haven’t been able to surpressjust yet, but are thrown in error, and are not to be concerned about. Let us know if the newest version works, and if not, we can escalate the case. Please also let us know where in your app this crash occurs.

Hey @Daniel M15Yes, we are experiencing it with the latest SDK version 14.1.0 as well and this crash is the most occurred crash in Firebase which happens on third-party libraries we depend on. So it would be better if you guys take this issue seriously and escalate its priority on your side.Thanks for your reply and willingness to help!
