swift-architecture

The best SwiftUI architecture depends on feature complexity, with MV or MVVM recommended for simple features and Clean Architecture or TCA for enterprise modules. A structured decision framework matches your specific feature requirements to the most suitable pattern.

To migrate from MVVM to TCA, evaluate your current architecture's fit and follow structured migration guidance that maps existing modules to the new pattern. This process involves assessing dependency injection and testability considerations to ensure a smooth transition between architecture patterns.

Use the Coordinator pattern in Swift when you need to manage navigation flow and routing separately from your view components. It is particularly effective for enterprise modules or complex feature flows where decoupling navigation logic improves testability and maintainability.

MVI vs TCA selection depends on your feature's state management complexity and unidirectional data flow requirements. The decision framework evaluates feature scope, testability needs, and dependency injection constraints to determine whether MVI or TCA better fits your Swift module.

Yes, the architecture guidance works for both single features and enterprise modules by scaling the decision framework accordingly. It evaluates pattern fit, dependency injection strategies, and testability considerations across different complexity levels, from individual SwiftUI views to large-scale module architectures.
