title: How to transition e.g. fade, from one view controller to another
body: <p>I have done a lot of research on Youtube, websites and Stack Overflow, but couldn't find anything that worked. Hopefully, you can help me. I have view controllers in Xcode, and buttons on them that perform segues, to show the next view controller. But when it changes view controllers with the button performing a segue (show), it brings the next view controller up from the bottom of the screen. How do I change the transition (or add a transition) to make them fade into each other.</p>
