Summary

In this chapter, you learned a lot. You gained some insight into what AR is, the basic workings of AR, and what you can do with it. Then you learned about the components that make up an excellent AR experience, and you implemented your first small AR experience by adopting Quicklook in an app to preview AR content in a real AR session.

Then you explored different ways to render content in an AR scene. You took a quick look at SpriteKit and SceneKit, and learned that SpriteKit is Apple's 2D game-development framework.
