didSelectRowAt called only on multitouch

What can make

detect only multitouch? If I tap with one finger it doesn't call

Here is my Code:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "bookingSettingsCell", for: indexPath) as! SettingsTableViewCell
if indexPath.row < 3 {
cell.settingTitle.text = dataForSetting[indexPath.row].first
if dataForSetting[indexPath.row].last != "Pencil" {
cell.settingValue.isHidden = true
cell.settingChangable.isHidden = true
cell.settingSwitch.isHidden = false
return cell

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
DispatchQueue.main.async(execute: {
if indexPath.row < 3 {
let destinationVC = self.storyboard?.instantiateViewController(withIdentifier: "DatePicker") as! DatePickerViewController
destinationVC.modalPresentationStyle = .overCurrentContext
destinationVC.delegate = self
self.present(destinationVC, animated: true, completion: nil)

UITableViewCell class:

class SettingsTableViewCell: UITableViewCell {
@IBOutlet var settingTitle: UILabel!
@IBOutlet var settingChangable: UIImageView!
@IBOutlet var settingValue: UILabel!
@IBOutlet var settingSwitch: UISwitch!

override func awakeFromNib() {
settingSwitch.transform = CGAffineTransform(scaleX: 0.65, y: 0.60)

You can handle the behavior of uitableviews's didSelectRowAt method after implementing the delegate methods of gesture recognizer. This prevents the undefined behavior of taps between uiview and tableViewCell and keeps the record of touches.

UIGestureRecognizerDelegate method:

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {
    println("in shouldReceiveTouch")
    gestureRecognizer.delegate = self
    if (touch.view == tableView){
        println("touching tableView list")
        return false
        println("touching elsewhere")
        return true
