  <p>My swift code returns this:</p>
  
  <pre><code>{
      date = "2016-08-25 18:16:28 +0000";
      observation = "";
      products =     (
              {
                  name = cafe;
                  quantity = 1;
              }
      );
      room = Platinium;
  </code></pre>
  
  <p>This is my code:</p>
  
  <pre><code>let para:NSMutableDictionary = NSMutableDictionary()
  let prod: NSMutableDictionary = NSMutableDictionary()
  
  para.setValue(String(receivedString), forKey: "room")
  para.setValue(observationString, forKey: "observation")
  para.setValue(stringDate, forKey: "date")
  
  for product in products{
      prod.setValue(product.name, forKey: "name")
      prod.setValue(product.quantity, forKey: "quantity")
      para.setObject([prod], forKey: "products")
  }
  </code></pre>
  
  <p>This is my input:</p>
  
  <pre><code>{
      name = coffe;
      quantity = 2;
  }
  {
      name = cappuccino;
      quantity = 1;
  }
  </code></pre>
  
  <p>This is output </p>
  
  <pre><code>{
      date = "2016-08-25 18:52:30 +0000";
      observation = "";
      products =     (
              {
                  name = cappuccino;
                  quantity = 1;
              }
      );
      room = Platinium;
  }
  </code></pre>
