Dependency Injection and Modular Architecture Questions

Designing injectable, testable, modular mobile applications. DI frameworks: Dagger/Hilt for Android, Swinject/Factory for iOS. Modular architecture benefits: feature isolation, parallel development, reduced build times, improved testability. Organizing dependencies: feature modules, shared modules, core modules. Managing complex dependency graphs across many modules. Trade-offs: increased complexity vs. maintainability benefits. Monorepo vs. multi-repo strategies for modular apps.
