MVVM directory structure for larger project
Key Additions: 1. Modularization: Break the app into separate modules (e.g., UserModule, ProductModule) to improve scalability and collaboration in large teams. 2. DependencyInjection: Using DI frameworks (like Swinject) to handle dependencies across the app, improving testability and flexibility. 3. Managers: More specific app-wide managers like PushNotificationManager, AnalyticsManager for cross-functional management. 4. Tests: Better structured tests with different types of testing (e.g., unit tests, UI tests, integration tests). 5. Documentation: More extensive documentation covering architecture, APIs, and other design considerations.
