To structure a large SwiftUI app for maintainability, apply modular architecture with clear module boundaries to decouple components. This approach improves testability, reduces regression risk, and organizes code into predictable data flows using dependency injection.

Choosing between MVVM and TCA for an iOS project depends on your data flow needs. MVVM offers predictable data binding, while The Composable Architecture (TCA) provides strict state management and modular composition, both supporting scalable app design and testable component isolation.

To set up dependency injection in a modular iOS architecture, wire core dependencies into separated feature modules to decouple components. This strategy enables independent testing, promotes clean architecture across teams, and establishes maintainable code organization.

Yes, you can use clean architecture patterns to break a monolithic iOS app into modular features with shared core services. This reorganization reduces complexity, speeds up team on-boarding, lowers regression risk, and enforces clear project structure boundaries.

You need modularization in a SwiftUI project when managing a large codebase that requires clear project structure and testability. Modularization decouples components, establishes clear module boundaries, and enables independent testing to reduce regression risk across teams.

Yes, VIPER architecture works with SwiftUI to provide predictable data flow alongside MVVM and TCA. These pattern guidance approaches help engineers design scalable iOS app architectures by ensuring testability, reuse, and clean architecture across modular components.
