title: Parse JSON data in swift
body: <p>I am trying to parse my json data in swift 3.0. I am using Alamofire 4.0+
  Here is my json</p>
  
  <pre><code>{
  "token": 
  
  "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJleHAiOjE1MDQ0MjgzNzgxMTF9.CNonyvtQbRgaqqkdPO5KwqpVaUmlGrpaTqlBxmvaX80",
  
  "expires": 1504428378111,
  
  "user": 
  [{"user_id":13,"user_first_name":"Himanshu","user_last_name":"Srivastava","full_name":"Himanshu Srivastava"}]
  }
  </code></pre>
  
  <p>Here is my model class to hold these values</p>
  
  <pre><code>import Foundation
  import ObjectMapper
  class LoginResult:Mappable{
      var token:String?
      var expires:Double?
      var users:[[String:Any]]?
      required init?(map:Map){
  
      }
  
      func mapping(map:Map)-&gt;Void{
          self.token &lt;- map["token"]
          self.expires &lt;- map["expires"]
          self.users &lt;- map["user"]
      }
  }
  </code></pre>
  
  <p>None of the solution available on internet worked for me. How can I parse this json and map to the model class? 
  Any help here?</p>
