title: Switching from one view controller to another automatically
body: <p>I have a project where a user fills in a web form, once the user hits submit it moves to a viewcontroller that shows a message "sent" or "error".</p>
  
  <p>How can I make it automatically move to the main view controller without pressing a button, after a certain amount of seconds (so it displays the message "sent" for approx 2 - 3 seconds then moves to the main vc)</p>
  
  <p>Any information would be highly appreciated, thankyou</p>
