        let countryDialingCode = prefixCodes[countryCode ?? "IN"] ?? nil
        return countryDialingCode
    }
}

Wonderful work developers! Finally find the code for executing!

    func configuration() {
        for code in NSLocale.isoCountryCodes  {
            let id = NSLocale.localeIdentifier(fromComponents: [NSLocale.Key.countryCode.rawValue: code])
            let name = NSLocale(localeIdentifier: "en_US").displayName(forKey: NSLocale.Key.identifier, value: id)
            
            let locale = NSLocale.init(localeIdentifier: id)
            
            let countryCode = locale.object(forKey: NSLocale.Key.countryCode)
            let currencyCode = locale.object(forKey: NSLocale.Key.currencyCode)
            let currencySymbol = locale.object(forKey: NSLocale.Key.currencySymbol)
            
            if name != nil {
                let model = Country()
                model.name = name
                model.countryCode = countryCode as? String
                model.currencyCode = currencyCode as? String
                model.currencySymbol = currencySymbol as? String
                model.flag = String.flag(for: code)
                model.extensionCode = NSLocale().extensionCode(countryCode: model.countryCode)
                list.append(model)
            }
        }
        self.tableView.reloadData()
    }

    }
    
    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        print("search = \(searchText)" )
        self.dupList = searchText.isEmpty ? list : list.filter({ (model) -> Bool in
            return model.name!.range(of: searchText, options: .caseInsensitive, range: nil, locale: nil) != nil
        })
