This chapter concludes the discovery of the eight behavioral patterns, as described by the gang of four. Moreover, this chapter concludes the book.

I wanted the book to be really easy to follow without adding complexity in the sample provided. This book is intended to be a reference for anyone who wants to implement design patterns with Swift.

There are some points that we have not covered, such as multi-concurrency access, Swift 2 special coding with closure, and so on. I think that these points don't occur in a learning book. The main purpose of the book is to easily find the appropriate pattern when needed and have an easy illustration to follow.

Well, you now have all the necessary information to structure your code in a scalable way. This will help you to structure your code properly, increase the performance of your code, and reduce maintenance costs.

I really thank you to have followed the book. Now, it's up to you to put this knowledge into practice.
