Microapps architecture in Swift. Feature modules.
Article Summary
Majid Jabrayilov explores how to break down monolithic iOS apps into independent, testable feature modules. The secret? Treating each feature as its own microapp.
This deep dive from Swift with Majid walks through implementing a microapps architecture in Swift using feature modules. The approach isolates features into separate frameworks with clear boundaries, making large codebases more maintainable and teams more autonomous.
Key Takeaways
- Each feature becomes an independent framework with its own coordinator and dependencies
- Protocol-based boundaries prevent tight coupling between feature modules
- Feature modules can be developed and tested in isolation from main app
- Shared dependencies live in separate frameworks to avoid circular references
Microapps architecture transforms monolithic iOS apps into modular, independently testable features that scale with growing teams.
About This Article
Large app development teams struggle to deliver features to QA independently. They have to wait for other features to finish before they can test their own work, which slows down parallel development.
Majid Jabrayilov shows how to create dedicated feature modules in Swift Package Manager. Each module, like Onboarding, only imports the dependencies it needs, such as DesignSystem. Teams can then build and send microapps to TestFlight for early feedback.
Teams can now work on multi-screen features like checkout flows without waiting for other work to finish. They deliver complete feature modules to QA independently, which removes bottlenecks in large app development cycles.
