Xcode 8 GM -- SQLite error code:6922, 'disk I/O error'

Question

I am in the process of re-releasing my iPhone app and now an executeFetchRequest on my UIManagedDocument gets an SQLite error code:6922. I have searched the internet and there is no SQLite error code 6922. Anyone seen this. Everything worked fine with Xcode 7.

Facing this issue even on xcode 8 after official launch. – Ingratitude

I'm having the same problem.. Anyone solved it yet? – Kristoforo

Made a terrible blunder that prompted this error for me: I was using the NSFileManager to delete a photo in the documents directory. I had passed a null photo name and the process attempted to delete the documents DIRECTORY ! It failed to delete but corrupted CoreData records. – Benedikt
