What mobile apps actually requires in 2026
2026 cross-platform default is React Native with Expo + EAS Build, supplanting Flutter for most consumer apps (faster JS ecosystem, better OTA via Expo Updates). Native iOS Swift + SwiftUI dominates fintech; native Kotlin + Compose dominates Android-first markets like India and Southeast Asia. A real senior mobile engineer ships in a single store-ready binary, handles push tokens, deep links, biometric auth, and App Tracking Transparency prompts. Builders who only know JS/RN without native debugging skills will wipe out on 20% of production bugs that require Xcode or Android Studio inspection.
