title: Difference between #import and @class
body: <p>i recently watched a tutorial where the speaker said that it makes no difference if you use:</p>
  
  <pre><code>#import "Class.h"
  </code></pre>
  
  <p>or:</p>
  
  <pre><code>@class Class;
  </code></pre>
  
  <p>And i have to say, my apps work the one way or the other. 
  But there have to be a difference right? So thought i ask you guys.</p>
  
  <p>Thanks in advance!</p>
