To keep your code clean you should think about moving screen design related code for your cells from UITableViewController into a UITableViewCell class.

Your UITableViewController` needs only to set the selected state of the cell as follows:

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
    guard let cell = tableView.cellForRow(at: indexPath) else { return }
    cell.setSelected(true, animated: true)
}

Your desired customisation can be implemented in a derrived UITableViewCell class by overriding var isSelected. With this solution you could have even different select colors for each cell.

class MyTableViewCell: UITableViewCell
{
    @IBOutlet weak var label:UILabel!

    override var isSelected: Bool
    {
        didSet{
            if (isSelected)
            {
                self.backgroundColor = UIColor.red
                if let label = label
                {
                    label.textColor = UIColor.white
                }
            }
            else
            {
                self.backgroundColor = UIColor.white
                if let label = label
                {
                    label.textColor = UIColor.black
                }
            }
        }
    }
}
