Before we start

Difficulty: Beginner | Easy | Normal | Challenging

This article has been developed using Xcode 12.2, and Swift 5.3

Prerequisites:

• I have already written an article on MVC, and the code in this article is based on that code
• This article leverages protocol

Terminology

Coupling: The degree of interdependence between software modules and classes

protocol: A blueprint on methods, properties, and requirements to suit a piece of functionality

Coupling

Coupling is the degree of interdependence between software modules, and how closely connected they are.

A low degree of coupling is seen as a good design since low coupling can assist with reuse as well as readability and maintainability.

If we are trying to move between View Controllers using a Storyboard, we might well use code that has prepare(for:sender) and use this to pass data to a DetailViewController.
