Protocols and Protocol Extensions

While watching the presentations from WWDC 2015 about protocol extensions and protocol-oriented programming (POP), I will admit that I was very skeptical. I have worked with object-oriented programming (OOP) for so long that I was unsure whether this new programming paradigm would solve all of the problems that Apple was claiming it would. Since I am not one who lets my skepticism get in the way of trying something new, I set up a new project that mirrored the one I was currently working on, but wrote the code using Apple's recommendations for POP. I also used protocol extensions extensively in the code. I can honestly say that I was amazed by how much cleaner the new project was compared to the original one. I believe that protocol extensions are going to be one of those defining features that set one programming language apart from the rest.

In this chapter, you will learn about the following topics:

How are protocols used as...
