Today we go over what protocol extensions are, how they work, and why they are so powerful, using Swift 4. First we go over the general structure of creating a protocol extension that extends the functionality of multiple objects. Next, we dive into overriding the default functionality of the protocol extension. Lastly, we cover how you can combine multiple protocols into a single protocol.
Apple itself has stated that Swift is meant to be a protocol oriented programming language. Once you can grasp the usefulness of Swift protocols and their extensions, 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 how to implement your protocol extensions across different data mode types.
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.
