The Secret Sauce to Scalable SwiftUI Apps: Coordinator Pattern Explained
The Coordinator pattern has been a popular in UIKit-based iOS applications for years, helping developers manage navigation flow and decouple view controllers. As SwiftUI continues to mature, developers have been adapting this pattern to fit SwiftUI’s declarative paradigm and state-driven approach. This article explores how to implement the Coordinator pattern in SwiftUI applications, from basic concepts to complex implementations, all within the context of MVVM architecture.

The Coordinator pattern centralizes navigation logic by removing it from individual views and placing it in dedicated coordinator objects. This separation , increases the code reusability, improves testability, creates cleaner, more focused views and makes navigation flows easier to modify and maintain.
Let’s begin with an example to illustrate this concept. We will start by defining an enum and list all the pages or views that the application will have. For simplicity, we will have only two pages.
