My app has started experiencing intermittent crashes for ios15 devices only. From the logs, the suspected region of crash involves realm threads for write or read or update and TableView reload. But Since the issue is pretty intermittent we are not able to pinpoint the cause of the crash? Does anyone have any suggestion to pinpoint the cause of the crash or what new update in ios15 would have led to this issue.?
Below is the Crash Log. From the Crash Analytics.
