Protocol-oriented programming is about so much more than just the protocol; it is actually a new way of not only writing applications A simple way of understanding the concept of a protocol is to know that it defines attributes, methods, and required tasks which are separated from functions. Protocol-Oriented Programming is a new programming paradigm ushered in by Swift 2.0. In addition to learning the concepts of Protocol Oriented programming, it also shows the reader how to reduce the complexity of their codebase using protocol extensions.
