import UIKit
class SearchBookVC: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchResultsUpdating, UISearchBarDelegate {
#IBOutlet weak var tableview: UITableView!
struct Books {
var name = String()
var board = String()
var classname = String()
var area = String()
var city = String()
}
var books = [Books(name: "Physics", board: "CBSE",classname:"XI",area:"Karnataka",city:"Bangalore"),
Books(name:"English",board:"CBSE",classname:"X",area:"Maharashtra",city:"pune"),
Books(name:"biology",board:"IB",classname:"XII",area:"Gujarat",city:"Rajkot"),
Books(name:"chemistry",board:"IB",classname:"X",area:"Gujarat",city:"Ahmedabad"),
Books(name:"Maths",board:"ICSE",classname:"IX",area:"Maharashtra",city:"Mumbai"),
Books(name:"Science",board:"ICSE",classname:"XII",area:"Karnataka",city:"Mysore")
]
var filteredBooks = [Books]()
let searchController = UISearchController(searchResultsController: nil)
override func viewDidLoad() {
super.viewDidLoad()
filteredBooks = books
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
definesPresentationContext = true
tableview.tableHeaderView = searchController.searchBar
searchController.searchBar.scopeButtonTitles = ["All","Name", "Board", "Class", "Area","City"]
searchController.searchBar.delegate = self
self.tableview.register(mycell.self, forCellReuseIdentifier: "cell")
// Do any additional setup after loading the view.
}
func applySearch(searchText: String, scope: String = "All") {
if searchController.searchBar.text! == ""
{
filteredBooks = books.filter { book in
let nameofbook = ( scope == "All") || (book.name == scope) || (book.board == scope) || (book.classname == scope) || (book.area == scope) || (book.city == scope)
return nameofbook
}
}
else
{
filteredBooks = books.filter { book in
let nameofbook = ( scope == "All") || (book.name == scope) || (book.board == scope) || (book.classname == scope) || (book.area == scope) || (book.city == scope)
return nameofbook && book.name.lowercased().contains(searchText.lowercased()) && book.board.lowercased().contains(searchText.lowercased()) && book.classname.lowercased().contains(searchText.lowercased()) && book.area.lowercased().contains(searchText.lowercased()) && book.city.lowercased().contains(searchText.lowercased())
}
}
self.tableview.reloadData()
}
func updateSearchResults(for searchController: UISearchController) {
let searchBar = searchController.searchBar
let selectedScope = searchBar.scopeButtonTitles![searchBar.selectedScopeButtonIndex]
applySearch(searchText: searchController.searchBar.text!,scope: selectedScope)
}
func searchBar(_ searchBar: UISearchBar, selectedScopeButtonIndexDidChange selectedScope: Int) {
applySearch(searchText: searchController.searchBar.text!,scope: searchBar.scopeButtonTitles![selectedScope])
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.filteredBooks.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! mycell
cell.bookname?.text = self.filteredBooks[indexPath.row].name
cell.Boardname?.text = self.filteredBooks[indexPath.row].board
cell.classtitle?.text = self.filteredBooks[indexPath.row].classname
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("Row \(indexPath.row) selected")
}
}

Can you try it this way:
Make an array of auto-completion text-field, one for each of the data source.
Let these text-fields to be invisible at first.
After you select values and click the search button, let the corresponding text-fields to be visible.
Not sure if it will meet your requirement, please leave comments if you have any problem.
