Today we go over an introduction to Swift protocols, how they work, and why they are so powerful, using Swift 4. First we go over the general structure of creating a protocol that other objects can conform to. Next, we dive into the different types of members that you might add to your protocol. Lastly, we cover how protocols can be a powerful solution to the problems in your code.
Apple itself has stated that Swift is meant to be a protocol oriented programming language. Once you can grasp the usefulness of Swift protocols, you'll be able to see how they can solve your coding problems and will probably change the way you write your code in general. Lastly, you'll have a full understanding of the composition of a protocol.
Some othe points that get covered are Swift Declare Class Func in Protocol, Why must a protocol operator be implemented as a global function, Is this a correct use of using protocols and delegate pattern in Swift, how to create delegates in swift, Usage of protocols as array types and function parameters in swift.
