Apple Page Control sample code gives black screen

Ive downloaded Apple's PageControl Sample Code to try to learn how to create lazily loaded pages as the user scrolls as mentioned in Matt Neuburg's programming iOS 11. However right out of the box as I scroll the picutres disappear and I get a black screen. Is that supposed to happen is there an error in the code.

Could you show your exact code ?

I tested it on a simulator w/no issues. Try launching it on the simulator/device again, not connected to Xcode, to see if your issue persists.
