2. Setting up the Controller for the Search Bottom Sheet

Let's open SearchBottomSheetController.swift file. We will mostly use the same code here as Search Bar. We would add a few more logic to handle a tap on a row and send data back to the main screen.

Let's write the code for setting up the table view and the search bar. Let's open SearchBottomSheetController.swift file, and put the following code there:

import UIKit

class SearchBottomSheetController: UIViewController {

    let searchSheet = SearchBottomSheetView()
    
    //MARK: the list of names...
    var namesDatabase = ["Marvin Cook","Samira Jimenez","Coral Hancock","Xander Wade","Terence Mcneil","Dewey Buckley","Ophelia Higgins","Asiya Anthony","Francesco Knight","Claude Gonzalez","Demi Decker","Casey Park","Jon Hendrix","Hope Harvey","Richie Alexander","Carmen Proctor","Mercedes Callahan","Yahya Gibbs","Julian Pittman","Shauna Ray"]
    
    //MARK: the array to display the table view...
    var namesForTableView = [String]()
    
    override func loadView() {
        view = searchSheet
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        
        //MARK: sorting the names list...
        namesDatabase.sort()
        
        //MARK: setting up Table View data source and delegate...
        searchSheet.tableViewSearchResults.delegate = self
        searchSheet.tableViewSearchResults.dataSource = self
        
        //MARK: setting up Search Bar delegate...
        searchSheet.searchBar.delegate = self
        
        //MARK: initializing the array for the table view with all the names...
        namesForTableView = namesDatabase
    }
}

//MARK: adopting Table View protocols...
extension SearchBottomSheetController: UITableViewDelegate, UITableViewDataSource{
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return namesForTableView.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(
            withIdentifier: Configs.searchTableViewID, for: indexPath) as! SearchTableCell
        
        cell.labelTitle.text = namesForTableView[indexPath.row]
        return cell
    }
}

//MARK: adopting the search bar protocol...
extension SearchBottomSheetController: UISearchBarDelegate{
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        if searchText == ""{
            namesForTableView = namesDatabase
        }else{
            self.namesForTableView.removeAll()

            for name in namesDatabase{
                if name.contains(searchText){
                    self.namesForTableView.append(name)
                }
            }
        }
        self.searchSheet.tableViewSearchResults.reloadData()
    }
}
