In part 1 of this iOS tutorial we will be learning about protocols and protocol oriented programming in Swift. We will understand what a protocol is and how to write one. We will learn how to have a class or a struct conform to a protocol. We will cover how to implement protocol extensions and discuss the benefits of protocol oriented programming and the value it can add to your code. Be sure to stick around for part 2 where we will learn how to implement a custom delegate and get a deeper understanding of the delegation design pattern. This tutorial uses Swift 4 and Xcode 9.
