Swift 3.0

Below is the code to delete item and to reload the data.

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

     let noteEntity = "Note" //Entity Name

     let managedContext = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext

     let note = notes[indexPath.row]

     if editingStyle == .delete {
        managedContext.delete(note)

        do {
            try managedContext.save()
        } catch let error as NSError {
            print("Error While Deleting Note: \(error.userInfo)")
        }

     }

    //Code to Fetch New Data From The DB and Reload Table.
    let fetchRequest = NSFetchRequest(entityName: noteEntity)

    do {
        notes = try managedContext.fetch(fetchRequest) as! [Note]
    } catch let error as NSError {
        print("Error While Fetching Data From DB: \(error.userInfo)")
    }
    noteTableView.reloadData()
}
