title: How to call a class function from within another classes extension in Swift
body: <p>So say if I have a Class A. Then I create a new swift file for class B where it would look like this:</p>
  
  <pre><code>extension Class A {
  
   public Class B: Superclass {
  
    public class func doSomething() { }
  
   }
  
  }
  </code></pre>
  
  <p>Now how would I make the call to <code>doSomething()</code> ?</p>
