With WWDC just a few weeks away, we are just around the corner to previewing the next iteration of Swift. As developers we are used to change, but many anticipate a sizable adjustment to Swift 3.0. With Swift 2.2 gaining so much industry approval, has the language evolved enough for production use?

This week I was also pleased to release a new Swift 2.2 book update. The supporting Github project was also updated with a new code example for recursive enums. Overall, it's been super getting your feedback! Stay tuned for my next essay that will review Swift Unit Testing.
