ios – Why is not the slider in my customized UITableViewCell reacting to the drag makes an attempt?

I am creating an app in UIKit, programmatically.
One display has a UITableView with customized cells, some have sliders inside. All cells present up and might be chosen. Different customized cell parts like buttons and textual content discipline react to interplay, however not the sliders.
Here is my code:

class CellWithSliderValues: UITableViewCell{
    @IBOutlet var slider: UISlider! = {
        let ctrl = UISlider()
//        coloration setup right here
        return ctrl
    // some labels
    override init(type: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        tremendous.init(type: type, reuseIdentifier: reuseIdentifier)
        // structure code, skipped for StackOverflow
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been carried out")

How the cell is created for the desk, with tag calculation skipped:

let cell = mainScreen.desk.dequeueReusableCell(withIdentifier: "CellWithSliderValues") as! CellWithSliderValues
                cell.slider.maximumValue = Constants.BEST
                cell.slider.minimumValue = Constants.WORST
                cell.slider.worth = currvalue
                // tag is ready right here
                cell.slider.addTarget(self, motion: #selector(sliderChange), for: .valueChanged)
                return cell

A part of the delegate that is named when clicking of the slider cell:

guard let cell = (mainScreen.desk.cellForRow(at: indexPath) as? CellWithSliderValues) else {return}

Lastly, the operate that needs to be referred to as when the slider is dragged however is rarely really referred to as (seen with breakpoints):

@objc func sliderChange(sender: UISlider){
        // get the values right here

The identical strategy did work with the textual content entry fields, so what am i doing fallacious right here? Is it due to the Slider not having delegates?
