Crash in iOS - [RLMRealm verifyThread]

Hi Team,
@Andrew_Morgan, @Jay
We are using Realm SDK for storing and retrieving data. While retrieving and processing the data we are seeing the crash " [RLMRealm verifyThread]" . Which is not reproducible every time i.e, out of twenty time’s one time it may or may not crash. We also made sure the all the operation i.e, reading and computation are happening on common queue.
Team, Kindly help us here to make the app crash free.
We would be happy that we can connect for the call.

Below is the Stack Trace for your kind information.

It’s going to be challenging to troubleshoot that error without having the code that produces it. The stack trace is a good start but just not enough information

Does this posting help? The MacOS app crashes on startup with 'RLMException', reason: 'Keychain returned unexpected status code: -25291'
