iOS: ObjectMapper mapping an array of objects without root field

Question

Suppose that I have a User object:

class User: Mappable {
    var username: String?
    var age: Int?
    var weight: Double!
    var array: [Any]?
    var dictionary: [String : Any] = [:]
    var bestFriend: User?                       // Nested User object
    var friends: [User]?                        // Array of Users
    var birthday: Date?

    required init?(map: Map) {

    }

    // Mappable
    func mapping(map: Map) {
        username    <- map["username"]
        age         <- map["age"]
        weight      <- map["weight"]
        array       <- map["arr"]
        dictionary  <- map["dict"]
        bestFriend  <- map["best_friend"]
        friends     <- map["friends"]
        birthday    <- (map["birthday"], DateTransform())
    }
}

And my Json contains an array of that object: [User] How can I map this array even if it has not a specific field name? This is what I did:

class Users: Mappable {

var users: [User]?

required init?(map: Map) {

        }

// Mappable
        func mapping(map: Map) {
          //What have I to put here??
        }

}

please before down voting explain why

It's quite simple you just have to use mapArray instead of map.

You just don't need to create new users class, only user class is enough to do this task

Use in this way

let arrUser = Mapper<User>().mapArray(JSONObject: JSONResponse.rawValue)
