Swift - not detect the event of moving the Slider in Custom Cell - ios

Question

I am developing an application in swift 3 with the following interface:
I have to add some details about the legend. The legend consists of two views (firstView and secondView). Where a default "layout" is 0, until we click on it and that is when the detail of the cell is opened. Bells, a legend like this appears:
Currently the slider send events are as follows:
The interface consists of two views. The map that is the view of the bottom ("MainMapVC") that if we make a "swipe" to the right appears the legend of the map "LefSideViewController" formed by custom cells ("customCell").
I enclose the code of the three classes:
The "customCell":
import UIKit
protocol customCellDelegate {
func didTappedSwicht(cell: customCell)
func didMoveSlider(cell: customCell)
}
class customCell: UITableViewCell {
//MARK: OUTLETS VIEW 1
#IBOutlet weak var firstView: UIView!
#IBOutlet weak var firstViewLabel: UILabel!
#IBOutlet weak var swichtActiveLayer: UISwitch!
//MARK: OUTLETS VIEW 2
#IBOutlet weak var secondView: UIView!
#IBOutlet weak var secondViewLabel: UILabel!
#IBOutlet weak var secondHeightConstraint: NSLayoutConstraint!
#IBOutlet weak var idDeliveryResponse: UILabel!
#IBOutlet weak var minRangeDeliveryResponse: UILabel!
#IBOutlet weak var maxRangeDeliveryResponse: UILabel!
#IBOutlet weak var initialMinDeliveryResponse: UILabel!
#IBOutlet weak var initialMaxDeliveryResponse: UILabel!
#IBOutlet weak var sliderOpacity: UISlider!
// MARK: VARIABLES
var delegate: customCellDelegate!
override func awakeFromNib() {
super.awakeFromNib()
}
func setupWithModel(model: deliveriesLeftTableModel){
firstViewLabel.text = model.firstViewLabel
secondViewLabel.text = model.secondViewLabel
idDeliveryResponse.text = model.idDeliveryResponse
minRangeDeliveryResponse.text = model.minRangeDeliveryResponse
maxRangeDeliveryResponse.text = model.maxRangeDeliveryResponse
initialMinDeliveryResponse.text = model.initialMinDeliveryResponse
initialMaxDeliveryResponse.text = model.initialMaxDeliveryResponse
swichtActiveLayer.setOn(model.swichtActiveLayer, animated: true)
sliderOpacity.value = model.sliderOpacity
}
#IBAction func swichtValueChanged(_ sender: Any) {
delegate.didTappedSwicht(cell: self)
}
#IBAction func primaryActionTrigger(_ sender: Any){
print("primaryActionTrigger")
}
#IBAction func touchUpInside(_ sender: Any){
print("touchUpInside")
}
/*#IBAction func sliderValueChanged(_ sender: Any) {
delegate.didMoveSlider(cell: self)
}*/
var showsDetails = false {
didSet {
secondHeightConstraint.priority = showsDetails ? 250 : 900
}
}
}
 
The "LefSideViewController" is:
import UIKit
protocol customCellDelegate {
func didTappedSwicht(cell: customCell)
func didMoveSlider(cell: customCell)
}
class customCell: UITableViewCell {
//MARK: OUTLETS VIEW 1

#IBOutlet weak var secondViewLabel: UILabel!
#IBOutlet weak var secondHeightConstraint: NSLayoutConstraint!
#IBOutlet weak var idDeliveryResponse: UILabel!
#IBOutlet weak var minRangeDeliveryResponse: UILabel!
#IBOutlet weak var maxRangeDeliveryResponse: UILabel!
#IBOutlet weak var initialMinDeliveryResponse: UILabel!
#IBOutlet weak var initialMaxDeliveryResponse: UILabel!
#IBOutlet weak var sliderOpacity: UISlider!
// MARK: VARIABLES
var delegate: customCellDelegate!
override func awakeFromNib() {
super.awakeFromNib()
}
func setupWithModel(model: deliveriesLeftTableModel){
firstViewLabel.text = model.firstViewLabel
secondViewLabel.text = model.secondViewLabel
idDeliveryResponse.text = model.idDeliveryResponse
minRangeDeliveryResponse.text = model.minRangeDeliveryResponse
maxRangeDeliveryResponse.text = model.maxRangeDeliveryResponse
initialMinDeliveryResponse.text = model.initialMinDeliveryResponse
initialMaxDeliveryResponse.text = model.initialMaxDeliveryResponse
swichtActiveLayer.setOn(model.swichtActiveLayer, animated: true)
sliderOpacity.value = model.sliderOpacity
}
#IBAction func swichtValueChanged(_ sender: Any) {

}
#IBAction func sliderValueChanged(_ sender: Any) {

}
var showsDetails = false {

}
}

The application communicates with protocols and delegates. For example, when we click on the swicht of the legend, the class "customCell" is able to detect the event "swichtValueChanged" and send it to a "didTappedSwicht" delegate of "LeftSideViewController", but when we move the slider the "customCell" class is not Able to detect the event "sliderValueChanged" and takes the event to close the view (because the legend on the left is closed with a swipe on the left).
How can I make it to detect the event of the slider and not to close the view?
Thank you

Answer 1

You should bind your Slider with two Events "Primary Action Triggered" and "Touch Up Inside"
Here I attached Image for your reference
and remove left swipe and right swipe gesture on this method
Method Description and code
1 "Primary Action Triggered"
When You click on slider the method will call "Primary Action Triggered"
Note : Disable your gesture
(UISwipeGestureRecognizerDirection.right and UISwipeGestureRecognizerDirection.left)
2 Touch Up Inside
Note : Enable your gesture both gesture
(UISwipeGestureRecognizerDirection.right and UISwipeGestureRecognizerDirection.left)
