title: Connecting an .xib-File to a Custom Class
body: <p>I have created a custom .xib-file and a custom subclass of <code>UIView</code>. 
  <strong>What is the procedure to connect the two?</strong> </p>
  
  <p>Meaning that when I set <code>MyCustomClass</code> in the custom class attribute, it turns into my custom .xib-file and acts according to MyCustomClass.swift.</p>
