Error with UIsearchbar results while selecting from tableview in swift iOS

Question

In my current application, I show a list of students. I give a check mark button for selection. I am able to select students from the table, but whenever I try to select from search bar results, it's not working correctly.

For example, in the list I selected the object at index 0 and 1; whenever I try to search something, the search bar results object at index 0 and 1 gets selected automatically. Why is that, and how can I fix it?

// MARK:- seachbar methods
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String){
        search_bar.showsCancelButton = true

        print("SERACH TEXT ",searchText)
        if searchText.isEmpty{
            is_searching = false
        } else {
            print(" search text %@ ",searchText as NSString)
            is_searching = true
            searchingDataArray.removeAllObjects()
            for index in 0 ..< studentsArray.count
            {
                var localDic :NSDictionary!
                localDic = studentsArray.object(at: index) as! NSDictionary
                let nameString = localDic["name"] as? NSString
                let regString = localDic["reg_no"] as? NSString

                if (nameString?.localizedCaseInsensitiveContains(searchText))! || (regString?.localizedCaseInsensitiveContains(searchText))!
                {
                    searchingDataArray.add(localDic)
                } else {
                    print("Not Exists")
                }

Try like this

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "SKTutorCell", for: indexPath) as! SKTutorCell

    var localDic :NSDictionary!

if is_searching
    {
        localDic = searchingDataArray.object(at: indexPath.row) as! NSDictionary

if ((searchingDataArray[indexPath.row] as AnyObject).isEqual("0")) {

    cell.checkMarkBtn.setImage(UIImage(named:"UnCheckIcon"), for: .normal)
}else{
    cell.checkMarkBtn.setImage(UIImage(named:"CheckIcon"), for: .normal)
}

}
else
{
    localDic = studentsArray.object(at: indexPath.row) as! NSDictionary


if ((studentcheckArray[indexPath.row] as AnyObject).isEqual("0")) {
    cell.checkMarkBtn.setImage(UIImage(named:"UnCheckIcon"), for: .normal)
}else{
    cell.checkMarkBtn.setImage(UIImage(named:"CheckIcon"), for: .normal)
}
}


    cell.nameRegdNoLbl.text = localDic?.value(forKey: "name") as? String

    cell.checkMarkBtn.tag = indexPath.row
    cell.checkMarkBtn.addTarget(self, action: #selector(checkBoxSelection(_:)), for: .touchUpInside)


    cell.seeProfileBtn.tag = indexPath.row
    cell.seeProfileBtn.addTarget(self, action: #selector(seeProfilAction(_:)), for: .touchUpInside)
    return cell
}
