Displaying the cities' information

The next step is to create a class to store the information received from the Internet. In this case, we can do it in a straightforward manner by copying the JSON object properties in our class properties. Create a new group called Models and, inside it, a file called CityInfo.swift. There you can code CityInfo as follows:

class CityInfo {
    var fcodeName:String?
    var wikipedia:String?
    var geonameId: Int!
    var population:Int?
    var countrycode:String?
    var fclName:String?
    var lat : Double!
    var lng: Double!
    var fcode: String?
    var toponymName:String?
    var name:String!
    var fcl:String?
    
    init?(json:JSON){){){
        // if any required field is missing we must not create the object.
        if let name = json["name"].string,,, geonameId = json["geonameId"].int, lat = json["lat"].double,
            lng = json["lng"].double {
            self.name = name
            self...
