Got two displays working with Set. One problem faced was with two view controllers. When the second screen was made, to save time with setting images for card buttons, I copy/pasted the cards into the other screen and connected them to the CardGame base class. What I didn’t realize is that the event bindings were still linked to the original view controller. When changing screens the controllers that are linked are deallocated and the methods are called on nil and fail silently. This was very hard to debug.
