Swift UITableView willSelectRowAt doesn't work properly

Question

In my tableView I want the cells to be unselectable.
So I wrote in my TableViewController:

override func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
    if indexPath.section == 0 {
        return nil
    } else {
        if switchIsOn! {
            return indexPath
        } else {
            return nil
        }
    }

}

It works as expected when I make a normal touch in the cells, but when I hold my finger down on the cell, it becomes selected anyway. How can I avoid this?

Answer 1

When switch state changes call tableView.reloadData(), then add this

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    ...

    if indexPath.section != 0 && !switchIsOn! {
        cell.selectionStyle = .none
    } else {
        cell.selectionStyle = .default
    }
    return cell

}
