title: making and presenting app tutorial views in Xcode
body: <p>I have an app that is not super intuitive. I want to take screenshots of the confusing screens and then use MSpaint to write instructions and doodles. When the user opens the view in the app for the first time, I want to present the series of altered screenshots along with an "OK" button. pressing OK will dismiss the screenshot and it will not be shown again. Is there an efficient way to do this? I am new to Swift and Xcode. Any help would be appreciated  </p>
