CoreData ManagedObjectContext Recursive Save Error

Question

Some users of mine are encountering a CoreData error when performing a save. I haven\'t been able to find any information online about this error or how to symbolicate the stack

Answer 1

I had the same problem with the Xcode8/ios10. The problem was due to a call to save core data context inside the following method.

- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller {
    [self methodCallingSaveContext];
}

The

methodCallingSaveContext

calls the save core data context. In order to break the recursive call I rewrote the method in the following way:

- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller {
        dispatch_async(dispatch_get_main_queue(), ^{
               [self methodCallingSaveContext];
         });
}

Now everything is working again.
