Examples for embedding React Native components into existing iOS applications with performance optimizations.
React Native Embedded App Example is a collection of practical code examples demonstrating how to integrate React Native components into an existing native iOS application. It solves the problem of incrementally adopting React Native without a full rewrite by providing patterns for performance optimization and communication between native and React Native code.
iOS developers with existing Objective-C/Swift applications who want to add React Native features incrementally, and React Native developers needing to embed their components within a larger native app.
Developers choose this project for its production-ready, performance-focused examples like bridge pre-loading and clear patterns for bidirectional communication, which address common hybrid app challenges not always covered in official documentation.

Demonstrates pre-loading the RCTBridge at app launch to reduce JavaScript load time and improve responsiveness, as detailed in the AppDelegate setup example.
Shows how to register and use different React Native modules as separate entry points, enabling modular feature adoption without codebase conflicts.
Provides advanced coordinator patterns for seamless data exchange between native and React Native components, solving common integration challenges.
Offers real-world scenarios like modal integration and data passing, making it ready for incremental React Native adoption in production apps.
Examples are written in Objective-C, which may not be directly applicable for teams using Swift, requiring additional effort to adapt.
Managing RCTBridge instances and delegates can be intricate, as highlighted in the advanced examples where coordinators are needed to avoid instance conflicts.
While pre-loading improves performance, it can lead to UI display delays if not handled properly, as discussed in the modal integration examples.
