title: Multiple methods to init object?
body: <p>I have a model which uses init with JSON, so that i can create objects directly from an API response. </p>
  
  <p>However in this instance I want to init the model and manually enter its properties, hence it wont be JSON. </p>
  
  <p>How can i have another init method that allows me to not use the standard JSON method and instead manually enter my params?</p>
  
  <p>The model looks like this...</p>
  
  <pre><code>class Conversation: NSObject {
  
      var id: String
      var index: String
      var image: String
      var firstname: String
      var lastname: String
      var withuserid: String
      var badgeCount: String
  
      init?(_ json: JSON) {
          guard let id = json["id"].string,
              let index = json["index"].string,
              let image = json["image"].string,
              let firstname = json["firstname"].string,
              let lastname = json["lastname"].string,
              let withuserid = json["withuserid"].string,
              let badgeCount = json["badgeCount"].string
  
              else { return nil }
  
          self.id = id
          self.index = index
          self.image = image
          self.firstname = firstname
          self.lastname = lastname
          self.withuserid = withuserid
          self.badgeCount = badgeCount
      }
  }
  </code></pre>
