How to Pass the array in multiple selected UISwitch tableViewCell rows into next view controller

Pass the array in multiple selected UISwitch tableViewCell rows into next view controller

var tableViewData = ["Some1", "Some2","Some3", "Some4"]
var tableViewBoolValues = [false, false, false, false]

I'm taking 2 arrays for displaying in TableView
MyTableView Code is here :-

//MARK: - TableView
extension CategoryListViewController : UITableViewDelegate, UITableViewDataSource, CategoryListDelegate {
    func didTap(on switchState: Bool, at index: Int) {
        tableViewBoolValues[index] = switchState
        tableview.reloadData()
    }
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return tableViewData.count
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CategoryListTableViewCell") as? CategoryListTableViewCell
        cell?.categoryLabel?.text = tableViewData[indexPath.row]
        cell?.switchButton.isOn = tableViewBoolValues[indexPath.row]
        cell?.categoryListDelegate = (self as CategoryListDelegate)
        cell?.tag = indexPath.row
        return (cell)!
    }
}

UITableViewCell Code is here :-

import UIKit

@objc protocol CategoryListDelegate: NSObjectProtocol{
    func didTap(on switchState:Bool, at index: Int)
}

class CategoryListTableViewCell: UITableViewCell {

    weak var categoryListDelegate: CategoryListDelegate?
    var indexPath : IndexPath?
    @IBOutlet weak var categoryLabel: UILabel!
    @IBOutlet weak var switchButton: UISwitch!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    @IBAction func switchButtonTapped(_ sender: UISwitch) {

        if (self.categoryListDelegate?.responds(to: #selector(CategoryListDelegate.didTap(on:at:))))! {
            self.categoryListDelegate?.didTap(on:sender.isOn, at: self.tag)
            if switchButton.tag  == indexPath?.row{    
            }
        }
    }
}

For example i'm clicking two rows tableViewBoolValues and tableViewData in TableViewCell, i need to pass that two selected rows tableViewBoolValues and tableViewData into another ViewController 

@IBAction func nextVCButtonTapped(_ sender: Any) {

     let storyBoard : UIStoryboard = UIStoryboard(name: "main", bundle:nil)
     let vc = storyBoard.instantiateViewController(withIdentifier: "AnotherViewController") as! AnotherViewControlle
     let selectedRows = tableview.indexPathsForSelectedRows
    // I got struct here 
     self.navigationController?.pushViewController(vc, animated: true)
}

Thanks in Advance..

You need to save the switch state of the cell's UISwitch with the data arrays. I would use a single array of dictionaries (or objects) for the table data and add an "isSelected" key to track the UISwitch states. Something like:

    var dataObject1 = ["data":"Some1", "boolValue":false, "isSelected": false] as [String : Any]
    var dataObject2 = ["data":"Some2", "boolValue":false, "isSelected": false] as [String : Any]
    var dataObject3 = ["data":"Some3", "boolValue":false, "isSelected": false] as [String : Any]
    var tableViewData = [dataObject1, dataObject2, dataObject3]

In cellForRow() set the UISwitch state to the "isSelected" key. In switchButtonTapped() set the "isSelected" key to the UISwitch state. In nextVCButtonTapped() create array with dataObjects where "isSelected" = true. Pass this array to newly created VC.
