title: Core Data & Generating Model Entities
body: <p>Standard newbie question. I've created a data model for an iOS application. I am able to create, update and delete entities within the model from various views by using the NSEntityDescription object. </p>
  
  <p>Say if I had a mutable array of objects returned from a fetch request. How can I loop through each one when I do not have a generated object definition from the entity model? By generated object definition I mean, a header and body class definition of the entity described in the data model package.</p>
