title: Propertys of Object's type "id"
body: <p>I would bet this is a very basic question, but i don't get it!</p>
  
  <p>I load some REST Data and put it in Objects in a NSMutableArray.</p>
  
  <ol>
  <li>Load REST-Data</li>
  <li>Parsing the Rest-Data to Objects</li>
  <li>Add the Objects to a NSMutable Array</li>
  </ol>
  
  <p>now i need to access some properties of the objects stored in the mutable array and i get Xcode errors, stating that there is no property with the given name in object of type "id".</p>
  
  <p>Could somebody give me a quick hint? I thought i could use the Objects and their properties within the NSMutable Array directly.</p>
  
  <p>Thanks for your help!</p>
