How to optimize performance across iOS and Android platforms.

To optimize performance across iOS and Android platforms, use cross-platform frameworks like Flutter or React Native, which allow code sharing while ensuring native performance. Focus on minimizing app size, managing memory efficiently, and optimizing API calls to reduce load times. Use platform-specific optimizations like Swift or Kotlin modules when necessary. Efficient code architecture, caching, and lazy loading can also enhance speed. Additionally, regularly test on both platforms to identify performance bottlenecks and ensure smooth user experience.
