reloading table view when search bar is empty - swift

Question

I am new in swift.I have implement the search operation for json show in table view about description field .
func updateSearchResults(for searchController: UISearchController) {
// If we haven't typed anything into the search bar then do not filter the results
if searchController.searchBar.text! == "" {
filteredsneakernews = [classObject.descriptionn]
self.results = self.placeHolderArray
self.DiscoveryNewsTableView.reloadData()
} else {
// Filter the results
//filteredsneakernews = [classObject.descriptionn].filter { $0.description.lowercased().contains(searchController.searchBar.text!.lowercased()) }
results = results.filter {
$0.description.lowercased().contains(searchController.searchBar.text!.lowercased()) }
// self.results = self.placeHolderArray
self.DiscoveryNewsTableView.reloadData()
}
// self.DiscoveryNewsTableView.reloadData()
}
Here is code for table view
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "discoveryNewscell") as! DiscoveryNewsTableViewCell
classObject.getDataForTableView(results: results, index: indexPath.row)
//let image_url = filteredsneakernews[indexPath.row].image
// cell.sneakerImageView.image=filteredsneakernews[indexPath.row].image
self.placeHolderArray = self.results
cell.newsTitle.text = classObject.descriptionn
let imageURLPathString = newsurl + classObject.image
let url1 = URL(string: imageURLPathString)
print("xyz", url1)
let data = try? Data(contentsOf: url1!)
if let imageData = data {
let image = UIImage(data: imageData)
cell.sneakerImageView.image = image
}
return cell
}
here is the class that i have made for getting data from json
class getData: NSObject {
var descriptionn : String = ""
var image : String = ""
// static let shared = getData()
func getDataForTableView(results: [[String:String]], index : Int){
var productArray = [String:String]()
productArray = results[index]
descriptionn = productArray["description"]!
image = productArray["images"]!
}
}
The search bar searching the result. when i finish the search when search bar is empty i want table view should reload the data .it should show the all record in table view when search bar is empty .but it is not reloading table view when search bar is empty .you can download the code from this link. https://drive.google.com/file/d/1G3QUYLgLDwIjNKb-HB-zO98l14HrcRVe/view?usp=sharing

#ajadka I have seen your code and there is small mistake ...just replace this line n it'll work correctly ..
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "discoveryNewscell") as! DiscoveryNewsTableViewCell
// self.placeHolderArray = self.results comment this line here
...... }
and put that line here
func single_news(userid: Int) {
.......
self.results = jsonValue.object(forKey: "data") as! [[String:String]]
self.placeHolderArray = self.results //put here that line
..........
}
