Помогите, пожалуйста, правильно заполнить СегментедКонтрол во вьюконтроллере(мои кейсы это перечень банков и tableviewcell с данными валюта-курс покупки и продажи.
Это моя ТейблвьюСел:

class tableViewCell: UITableViewCell {
@IBOutlet weak var nameCurrency: UILabel!
@IBOutlet weak var exchangeRates: UILabel!
override func awakeFromNib() {
    super.awakeFromNib()
}
  func configure(exchangeRate: Bank, index: Int) {
self.nameCurrency.text = exchangeRate.rates[index].name
self.exchangeRates.text = " \(exchangeRate.rates[index].ask)  / \(exchangeRate.rates[index].bid)"
}
}

And ViewController with registered Cell:

class ExchangeViewController: UIViewController, UITableViewDelegate, UIScrollViewDelegate, UITableViewDataSource {
var zxc: Int!
private struct Constants {
    static let exchangeTableViewCellId = "customCell"
}
 var ratesSectionsArray = [Bank]()
@IBOutlet weak var tableView: UITableView!
@IBOutlet weak var segLabel: UISegmentedControl!
@IBAction func switchCustomBank(_ sender: UISegmentedControl) {
    switch segLabel.selectedSegmentIndex {
    case 0:
    case 1:
    case 2:
    case 3:
    default:
    }
override func viewDidLoad() {
    super.viewDidLoad()
    
    let nib = UINib(nibName: Constants.exchangeTableViewCellId, bundle: nil)
    tableView.register(nib, forCellReuseIdentifier: Constants.exchangeTableViewCellId)
    zxc = 0
   let baseUrlString = "http://resources.finance.ua/ru/public/currency-cash.json"
    guard let url = URL(string: baseUrlString) else { return }
    URLSession.shared.dataTask(with: url) {
        (data, response, error) in

                guard let jsonDict = json as? [String: Any],
                    let organizationsArray = jsonDict["organizations"] as? [[String: Any]]
                else {return}
                for organization in organizationsArray{
                   guard let bank = Bank(json: organization)
                        else { continue }
                    self.ratesSectionsArray.append(bank)
                }
                DispatchQueue.main.async {
                    self.tableView.reloadData()

В тексте ошибки, если не читать лишнюю информацию, все написано.

Это значит что вот в этом месте
let nib = UINib(nibName: Constants.exchangeTableViewCellId, bundle: nil)
вы передаете строку Constants.exchangeTableViewCellId(в которой хранится переменная со значением customCell) , но xib с таким названием в проекте у вас нет. Полагаю, что вы ошиблись в названии.

Можно попробовать так

Bank 
class Bank: Codable {
let sourceID, date: String
let organizations: [Organization]
let orgTypes, currencies, regions, cities: [String: String]

enum CodingKeys: String, CodingKey {
    case sourceID = "sourceId"

init(sourceID: String, date: String, organizations: [Organization], orgTypes: [String: String], currencies: [String: String], regions: [String: String], cities: [String: String]) {
    self.sourceID = sourceID
    self.date = date
    self.organizations = organizations
    self.orgTypes = orgTypes
    self.currencies = currencies
    self.regions = regions
    self.cities = cities
}
}

class Organization: Codable {

    self.oldID = oldID

TableView 
class TableViewController: UITableViewController {

var ratesSectionsArray: [Bank] = []


override func viewDidLoad() {
    super.viewDidLoad()

}



override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    let baseUrlString = "http://resources.finance.ua/ru/public/currency-cash.json"
    guard let url = URL(string: baseUrlString) else { return }
    let session = URLSession.shared

    let task = session.dataTask(with: url) { (data, _, _) in
        guard let data = data else { return }
        do {
            let bankData = try! JSONDecoder().decode(Bank.self, from: data)

            self.ratesSectionsArray = [bankData]

            DispatchQueue.main.async {
                self.tableView.reloadData()

            }
        } catch {
        }
    }
    task.resume()
}


override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    if ratesSectionsArray.count >= 1 {
        return ratesSectionsArray[0].organizations.count
    } else {
        print(ratesSectionsArray)
        return 1
    }
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell

    if ratesSectionsArray.count >= 1 {
        cell.nameCurrency.text = ratesSectionsArray[0].organizations[indexPath.row].title

        let ask = ratesSectionsArray[0].organizations[indexPath.row].currencies["EUR"]?.ask as! String
        let bid = ratesSectionsArray[0].organizations[indexPath.row].currencies["EUR"]?.bid as! String

        cell.exchangeRates.text = " ask \(ask)    bid  \(bid))"
    } else {
    }

    return cell

Спасибо огромное, особенно Psilc.
Это почти готовый код, даже с большей информацией чем я могла подумать!
