I have a TableView with cells that when pressed anywhere in the cell, it adds a checkmark on the right. I only want the checkmark to show up if the cell is tapped on the right side. Here's the pertinent section of code from the TableViewController:

```
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "TaskCell", for: indexPath) as! TaskCell

        let task = tasks[indexPath.row]
            cell.task = task

        if task.completed {
            cell.accessoryType = UITableViewCellAccessoryType.checkmark;
        } else {
            cell.accessoryType = UITableViewCellAccessoryType.none;
        }

        return cell
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: false)

        var tappedItem = tasks[indexPath.row] as Task
        tappedItem.completed = !tappedItem.completed
        tasks[indexPath.row] = tappedItem

        tableView.reloadRows(at: [indexPath], with: UITableViewRowAnimation.none)
    }

}

```

Is there a simple way to do that, or to do it using storyboard? My Swift skills leave a LOT to be desired. Any help would be appreciated! Thank you!
