Recently updated one of my iOS games. While doing this I realized how much Objective C and Metal is really behind SpriteKit and other APIs. I felt like Alice going through the mirror and finding myself in an unfamiliar land. Looking at what makes up the API’s is really insightful to see how it’s works under the hood. Every time that I need to use a new API, I always take a look at the source code to gain more insight. Let's go exploring!
