help you fix your problem so now looking at your code every time you access appDel.managedObjectContext you are creating a new instance. when the old instance is gone you won't be able to access the data as well and you have to refetch everything. so make sure that you use only one instance. and it would be better for GUI context to have main concurrency.
code :
var managedObjectContext: NSManagedObjectContext {

   if (_managedObjectContext)
    {
        return _managedObjectContext; // making sure you don't reinitialise 
    }
        let coordinator = self.persistentStoreCoordinator

            _managedObjectContext = NSManagedObjectContext(concurrencyType: NSManagedObjectContextConcurrencyType.MainQueueConcurrencyType)
            _managedObjectContext!.persistentStoreCoordinator = coordinator


    return _managedObjectContext!
}

UIRefreshControl not Dissapearing

UIRefreshControl not Dissapearing

it fixes the issue The pull to refresh is not disappearing. There is only 3 rows visible on the screen and after using print(indexPath.row) I can see that it is reloading rows 0,1,2 again but the refresh control is not disappearing. , First, this line is wrong:
code :
tableView.addSubview(refreshControl!)...}
tableView.refreshControl = refreshControl
        dispatch_async(dispatch_get_main_queue(), {
            self.tableView.reloadData()
            self.tableView.refreshControl.endRefreshing()
        })
