Answer 1

For Swift 4.1 (tested code)

import UIKit
import SwiftyJSON

class UserObject: NSObject, NSCoding {
    var username: String? = ""
    var userID: String? = ""
    var user_email: String? = ""
    var name: String? = ""
    var age: String? = ""
    var gender: String? = ""

    override init() {
        super.init()
    }

    init(dictionary: JSON) {
        //User data initialize...
        username = dictionary["username"].stringValue
        userID = dictionary["iUserID"].stringValue
        user_email = dictionary["email"].stringValue
        name = dictionary["name"].stringValue
        age = dictionary["age"].stringValue
        gender = dictionary["gender"].stringValue
    }

    required public init(coder aDecoder: NSCoder) {
        username = aDecoder.decodeObject(forKey: "username") as? String
        userID = aDecoder.decodeObject(forKey: "iUserID") as? String
        user_email = aDecoder.decodeObject(forKey: "email") as? String
        name = aDecoder.decodeObject(forKey: "name") as? String
        age = aDecoder.decodeObject(forKey: "age") as? String
        gender = aDecoder.decodeObject(forKey: "gender") as? String
    }

    func encode(with aCoder: NSCoder) {
        aCoder.encode(username, forKey: "username")
        aCoder.encode(userID, forKey: "iUserID")
        aCoder.encode(user_email, forKey: "email")
        aCoder.encode(name, forKey: "name")
        aCoder.encode(age, forKey: "age")
        aCoder.encode(gender, forKey: "gender")
    }
}

Note : NSCoding protocol is important
