Getting Started with iOS App Modularization: Final Extraction and Micro-App

Tokopedia's iOS team just wrapped up their modularization tutorial series, and the final piece is a game-changer: micro apps that let you build only what you need.

This is part 3 of Tokopedia Engineering's hands-on iOS modularization guide. Engineer Arya Surya walks through extracting the Product Detail feature into its own framework, then introduces micro apps as development playgrounds for individual features.

Key Takeaways

• Extract Product Detail into standalone framework with proper ACL and dependencies
• Create micro app targets within frameworks for isolated feature development
• Build only necessary features instead of compiling the entire monolith app
• Tokopedia achieved 1000% faster build times using this modular approach with Bazel

The tutorial includes a complete GitHub repo with working code, plus Tokopedia's story about how they scaled this approach to achieve 10x build time improvements.
