If you want a step-by-step understanding of how to create an InAppManager and InAppObserver class, this is the course for you!
If you don't care about creating those classes from scratch and just want to jumpstart into using in-app purchases, this is ALSO the course for you. You're welcome to skip ahead to the Quick Start guide (and copy our InAppManager and InAppObserver classes). You can begin testing purchases or creating an in-game money system within an hour.
Included with the tutorial movies are two source projects, one uses the Sprite Kit template and another uses the starting template for Single View Application. These projects alone make for a valuable reference, but you'll get three hours of tutorials explaining every detail! The source projects have been added to the final movie in the Supplemental Materials tab.
