title: Error: unreachable because it has no entry points
body: <p>Using Swift I got the error that my "TableViewController" is unreachable because it has no entry points and no runtime access via [UIStoryboard instantiateViewControllerWithIdentifier]. </p>
  
  <p>In my View Controller class there is the suggestion to fix it while changing <code>instantiateViewController(withIdentfier...)</code> in <code>instantiateViewController(withIdentifier)</code>. </p>
  
  <p>Shall I do this or how do I fix this?</p>
