How to swipe to delete on tableview cell

Just need 3 delegate methods:
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView
           editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
  
    NSUInteger row = [indexPath row];
    NSUInteger count = [savedTask count];
  
    if (row < count) {
        return  UITableViewCellEditingStyleDelete;
    } else {
        return UITableViewCellEditingStyleNone;
    }
}

/*
 *Commit delete action
 */
- (void)tableView:(UITableView *)tableView
commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath {
  
    NSUInteger row = [indexPath row];
    NSUInteger count = [savedTask count];
  
    if (row < count) {
        NSMutableArray* temparr = [[NSMutableArray alloc] initWithArray:savedTask];
        [temparr removeObjectAtIndex:row];
        savedTask = temparr;
    }
}

- (void)tableView:(UITableView *)tableView
didEndEditingRowAtIndexPath:(NSIndexPath *)indexPath {
  
    [tableView reloadData];
}
