Can it help with mobile security concerns?

Absolutely. It provides mandatory patterns for secure token storage using platform-native encrypted storage instead of insecure defaults like AsyncStorage.

Does this skill support cross-platform frameworks?

Yes, it provides specific guidance and performance optimizations for React Native and Flutter, in addition to native iOS (Swift/SwiftUI) and Android (Kotlin/Compose) development.

How does it improve mobile app performance?

It enforces strict rules for hardware acceleration, efficient list rendering (using FlatList or ListView.builder), and prevents common AI mistakes like unnecessary state rebuilds.

Does it handle platform-specific UI differences?

Yes, it includes a platform decision matrix to help determine when to unify the UI and when to diverge to respect iOS edge swipes or Android system back buttons.
