iOS 10 Core Data Exception Code error: (6922)

We're experiencing an exception from our SQL database while trying to migrate Core Data on iOS 10. The exception is thrown but it seems the migration still succeeds. We do a manual migration then MagicalRecord handles the rest of the setup. Has anyone else experienced this before/ knows how to resolve this?

Error output:

    CoreData: error: (6922) I/O error for database at /var/mobile/Containers/Data/Application/9CA333FB-49CB-4168-B26A-A6F6E6CF94C7/Documents/Messaging.sqlite.  SQLite error code:6922, 'disk I/O error'

I encountered this issue today after upgrading to Xcode 11 beta 5.

Running the command to reset all of my simulators corrected it for me:

xcrun simctl erase all
