I’m putting together an app that shows managers on Page1 and their respective employees on Page2. I decided to mount a plist and press a Tableview, see:
To load the plist correctly insert to Appdelegate the following code:
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        if let url = Bundle.main.url(forResource: "directory", withExtension: "plist"), let array = NSArray(contentsOf: url) as? [[String:Any]] {
            Shared.instance.employees = array.map{Employee(dictionary: $0)}
        }
        return true
}
I also have this Structure helping me with all this:
struct EmployeeDetails {
    let functionary: String
    let imageFace: String
    let phone: String
    init(dictionary: [String: Any]) {
        self.functionary = (dictionary["Functionary"] as? String) ?? ""
        self.imageFace = (dictionary["ImageFace"] as? String) ?? ""
        self.phone = (dictionary["Phone"] as? String) ?? ""
    }
}
struct Employee {
    let position: String
    let name: String
    let details: [EmployeeDetails] // [String:Any]
    init(dictionary: [String: Any]) {
        self.position = (dictionary["Position"] as? String) ?? ""
        self.name = (dictionary["Name"] as? String) ?? ""
        let t = (dictionary["Details"] as? [Any]) ?? []
        self.details = t.map({EmployeeDetails(dictionary: $0 as! [String : Any])})
    }
}
struct Shared {
    static var instance = Shared()
    var employees: [Employee] = []
}
So far so good, but I inserted a Searchbar that shows me the correct results, but when I play "Suzan Brown," I see the employees of "John Smith,". I don’t know if the mistake is in segue... Could someone help me? Below, my Tableviewcontroller, I know there is something wrong, but I do not know exactly what...
class Page1: UITableViewController, UISearchBarDelegate {
    @IBOutlet weak var searchBar: UISearchBar!
    var employeesSearching = [Employee]()
    var isSearching : Bool = false
    override func viewDidLoad() {
        super.viewDidLoad()
        self.searchBar.delegate = self
    }
    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if self.isSearching == true {
            return self.employeesSearching.count
        } else {
            return Shared.instance.employees.count
        }
    }
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell1
        let employee = Shared.instance.employees[indexPath.row]
        if self.isSearching == true {
            cell.nameLabel.text = self.employeesSearching[indexPath.row].name
            cell.positionLabel.text = self.employeesSearching[indexPath.row].position
        } else {
            cell.nameLabel.text = employee.name
            cell.positionLabel.text = employee.position
        }
        return cell
    }
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        if self.searchBar.text!.isEmpty {
            self.isSearching = false
            self.tableView.reloadData()
        } else {
            self.isSearching = true
            self.employeesSearching.removeAll(keepingCapacity: false)
            let searchText = self.searchBar.text!.lowercased()
            for employee in Shared.instance.employees {
                if employee.name.lowercased().range(of: searchText) != nil {
                    self.employeesSearching.append(employee)
                }
            }
        }
            self.tableView.reloadData()
    }
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if let destination = segue.destination as? Page2,
            let indexPath = tableView.indexPathForSelectedRow {
            destination.newPage = Shared.instance.employees[indexPath.row]
        }
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}
						
In your numberOfRowsInSection function switch to
return isSearching ? employeesSearching.count : Shared.instance.employees.count– Leo Dabus
In its function cellForRowAt
if self.isSearching == true {is redundant switch toif isSearching {– Leo Dabus
In this case use
self.isSearchingandisSearchingmakes no difference?– Arnon
It does not differentiate any. There are exceptions but most of the time you do not need to specify self
