The search bar in my app isn't working. Ive narrowed down the problem to the method cellforRowAt. It's not able to show the search result when words are typed in. The cellforRowAt contains the information of the filtered articles in the indexpath. How do I resolve this ?

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { //determines what data source should be used when user types
if isFiltering{
return filteredArticles?.count ?? 0
}
return articles?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell1", for: indexPath) as! NewsTableViewCell
let news: Articles
filteredArticles = articles
if isFiltering{
news = filteredArticles![indexPath.row]
}
else{
news = articles![indexPath.row]
}
cell.authorName.text = filteredArticles?[indexPath.row].author
cell.headLine.text = filteredArticles?[indexPath.row].title
cell.newsImage.downloadImage(from:(self.filteredArticles?[indexPath.item].urlImage ?? "nill"))
cell.timePublication.text = filteredArticles?[indexPath.row].publishedAt
if let dateString = filteredArticles?[indexPath.row].publishedAt,
let date = indDateFormatter.date(from: dateString){
let formattedString = outDateFormtter.string(from: date)
cell.timePublication.text = formattedString
} else {
cell.timePublication.text = "----------"
}
return cell
}
func updateSearchResults(for searchController: UISearchController) {
let searchBar = searchController.searchBar
filterContentForSearchText(searchBar.text!, articles!)
}
func filterContentForSearchText(_ searchText:String ,_ category: [Articles]){
filteredArticles = articles?.filter({ (article:Articles) -> Bool in
return article.description.lowercased().contains(searchText.lowercased())
})
table_view.reloadData()
}
