How to search data in tableview? - ios

Question

I have data in local file, I have loaded them into the tableView, and now I want to search/filter via search bar.
I have tried some solutions I've found on the Internet, but I don't know how to access specific data in my structure.
Here is part of the structure:
struct Model: Codable {
var data: [Description]
}
struct Description: Codable {
var id: Int
var name: String
var address: String
var city: String
var description: String
var countryId: Int
var webSite: String
var status: Int
var accountType: Int
var addDate: String
var placeGroupId: Int
var longitude: Double
var latitude: Double
var distance: Double
var working: Bool
var promotion: String
var repertoire: Repertoire
var workingHour: WorkingHour
var country: Country
var reviewNum: Int
var score: Double
var placeImgUrl: String
}
var model: Model?
and here is some code from my ViewController:
var filteredObjects = [Description]()
let searchController = UISearchController(searchResultsController: nil)
func searchBarIsEmpty() -> Bool {
return searchController.searchBar.text?.isEmpty ?? true
}
func filterContentForSearchText(_ searchText: String, scope: String = "All") {
}
extension ViewController: UISearchResultsUpdating {
func updateSearchResults(for searchController: UISearchController) {
<#code#>
}
}
I have variable model, which is type of struct Model. Structure Model have a variable data which is type of struct Description. And finally, in structure Description I have variable name. My tableView cells shows names of models (model?.data[indexPathrow.row].name). Now, I need to search by names shown in tableView cells. I hope I explained it clearly. Thank You very much!

Assuming objects is also [Description] and represents the data source array
func updateSearchResults(for searchController : UISearchController)
{
let searchString = searchController.searchBar.text!
if searchString.isEmpty {
filteredObjects.removeAll()
} else {
filteredObjects = objects.filter{ $0.name.range(of: searchString, options: .caseInsensitive) != nil }
}
tableView.reloadData()
}
In the table view data source methods display objects or filteredObjects depending on searchController.isActive
