SwiftUI's built-in navigation tools work well for small apps but create architectural problems at scale, including scattered navigation logic, tight coupling between views, and untestable code. The coordinator pattern addresses these issues by centralizing navigation logic, removing coupling, enabling dependency injection into view models, supporting deep linking, and making navigation testable through unit tests. The article demonstrates how to integrate coordinators with MVVM in SwiftUI, showing practical examples of handling value-destination links, view-destination links, and deep link management.
