Example Concept: Use lazy loading for images and data, which ensures that only necessary resources are loaded into memory when needed. Implement memory caching strategies to store frequently accessed data without redundant allocations. On iOS, leverage SwiftUI's declarative syntax for efficient UI updates, while on Android, use Jetpack Compose's recomposition model to minimize unnecessary UI redraws. Both platforms benefit from profiling tools like Xcode Instruments and Android Profiler to identify memory leaks and optimize resource usage.
