Coredata Error “data: <fault>”

I try to iterate through a data fetched from SQLite database using Core data. I store all fetched data from CoreData in NSMutableArray. When I iterate using for loop in this array only I can get first element in the array but the rest of element get me this error:

<Task: 0xf18b390> (entity: Task; id: 0xf18a700 <x-coredata://7388F0B7-E583-4BF0-BE64-08AD014EC583 /Task/p104> ; data: <fault>

below the code I’m using:

dispatch_sync(classificationQueue, ^{
    NSMutableArray *waitingTasks  = [[NSMutableArray alloc]initWithArray:[self getInsepectorTaskByTaskStatus:managedObjectContext :TASKSTATUSWAITING:CLASSIFICATIONFORMTYPE]];

    for (Task *cTask in waitingTasks){
        //Here when print cTask nsmanagedobject get me fault data
        NSLog(@"BBBBBBB %@",cTask);
        corporateName = [[NSString alloc]initWithString:(classificationWaitingTask.corporate.corporateTitle?classificationWaitingTask.corporate.corporateTitle:@"-")];
        [self performSelector:@selector(sendingClassificationForm:) withObject:classificationWaitingTask];
 sleep(0);

    }
}

This is resolve occurring data :fault

NSFetchRequest *taskDataRequest = [[NSFetchRequest alloc]init];
NSEntityDescription *dataEntityResultForm = [NSEntityDescription entityForName:@"Task" inManagedObjectContext:managedObjectContext];
[taskDataRequest setEntity:dataEntityResultForm];
//Note: Resolove problem happen data:fault by this properites 
[taskDataRequest setReturnsObjectsAsFaults:NO];
