title: Changing Class TableViewController.swift
body: <p>I have a <code>TableViewController</code>, with some cells. The cells have different background color and text in them. While testing the application their was no problem, but I needed to add a class to the <code>TableViewController</code>, so I went to the "custom class" tab and typed in the class, After that, my <code>TableViewController</code> just loads up empty. Why is that? </p>
  
  <p>It only happens when I change the class. </p>
