body: <p>I just declared an entity called "Users" array: </p>
  
  <pre><code>var UsersArray = [Users]()
  </code></pre>
  
  <p>I got this error:</p>
  
  <blockquote>
    <p>use of unresolved identifiers "Users" </p>
  </blockquote>
  
  <p>hint : I did import CoreData and created the entity </p>
