title: How to write efficient app tutorials iOS
body: <p>I would like to add instructions on how to use the app the first time the user logs in. I realize that this requires a lot of UI and coding work. My question is: Since the code will only be run at most one time, is there a more efficient way of adding it in other than adding it like normal UI and code? Do I mix the code for the ViewControllers together? Won't this get confusing? Won't it take up storage that is essentially pointless after the first 5 minutes? </p>
  
  <p>Any tips on creating a tutorial on a separate level, over the code of the actual app would be very helpful.</p>
  
  <p>Thank you.</p>
