title: launch screen customising
body: <p>I'm new to swift and Xcode, and I'd like to know is there anyone willing to explain to me how exactly should I make my launch screen to show for 3 seconds and in that time slightly fades out?</p>
  
  <p>I want to do a web view of a web page that I built previously, but want it to do the launch screen with fading before.</p>
  
  <p>I've read all other questions related to the topic, but I don't understand them. Also have been following some tutorials on the subject, but nothing.</p>
  
  <p>Anyone, please?</p>
