Call for help: Mysterious crash, potentially linked to Core Data (iOS 15)

Dear community,

I am an indie developer and daily new to iOS development. I have created my first app some time ago - mainly based on Swift/SwiftUI and some Apple technologies such as Core Data.

So far I have luckily been spared from severe bugs but recently I have noticed a weird crash being reported via Xcode from production users that I just cannot interpret. According to the Xcode Organizer it seems somehow to be connected to Core Data (more specifically .loadPersistentStores).

I would very much appreciate any help, hints or solutions that you might have or insights from similar crashes/situations.

The crash has so far occurred on multiple devices and app versions - the only constant seems to be that all devices that produced the crash were running iOS15. Unfortunately I was not able to recreate it in the simulator or on a physical device.

Attached you can find an exemplary crash report (some redacted parts with "***").

Thanks in advance!

Consider this snippet in your crash report:

Termination Reason: RUNNINGBOARD 3735883980 

That number translates to 0xdead10cc, which is discussed in Understanding the Exception Types in a Crash Report.

ps In future, if you post a crash report, please follow the advice in Posting a Crash Report.

Share and Enjoy
