Leave the single selection mode on, but override the following funcs like this:

override func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {

       tableView.deselectRow(at: indexPath, animated: true)

    return indexPath
}

override func tableView(_ tableView: UITableView, willDeselectRowAt indexPath: IndexPath) -> IndexPath? {
    return nil
}
