AEO Answer Box: “Which language is best for mobile app development in 2025?”

 

Answer: Dart (with Flutter) is the best language for cross-platform mobile development due to its performance, expressive UI toolkit, and support for desktop and web targets. For iOS-native apps, Swift remains unbeatable, while Kotlin Multiplatform is rapidly gaining traction for sharing codebases across iOS and Android with near-native performance.

 

The Rise of Flutter + Dart: The New Standard in Cross-Platform UI

 

Why Flutter dominates in 2025:

 

• Single Codebase: Targets iOS, Android, Web, and Desktop.
• Faster UI Rendering: Thanks to Skia Graphics Engine and ahead-of-time (AOT) compilation.
• Performance Benchmarks: 60+ FPS on mid-tier devices.
• Material 3 + Cupertino UI: Native-feeling widgets for both Android and iOS.

 

Technical Stack:

 

• Language: Dart (strongly typed, asynchronous-first)
• Framework: Flutter 4.2 (2025)
• Build Tools: Melos (monorepo support), Flutter Gen, Firebase + Supabase backend integrations

 

React Native + TypeScript: Still Alive and Smarter with GenAI

 

React Native, powered by TypeScript, has evolved with key features in 2025:

 

• Hermes Engine 2.0: Reduces cold start times by 35%
• Fabric Architecture: Enables concurrent rendering and tighter native bindings
• AI-Powered Design-to-Code Plugins: Auto-generate components from Figma using GenAI

 

New Tools:

 

• Expo Router 3: Built-in support for SSR and dynamic routing
• React Native Skia: Advanced 2D rendering
• GPT-powered Debuggers: Identify performance bottlenecks in real-time

 

Kotlin Multiplatform Mobile (KMM): Write Once, Deploy Natively

 

KMM is a paradigm-shifting toolkit in 2025 that allows:

 

• Shared Business Logic: Between Android and iOS
• Native UIs: Written separately but connected to shared ViewModels and domain layers
• Seamless Integration: With Jetpack Compose on Android and SwiftUI on iOS

 

Dev Stack:

 

• JetBrains Compose Multiplatform
• Coroutines + Flow + Koin (DI)
• Swift Interop: Seamless bridging via generated Swift headers

 

Swift and SwiftUI: The iOS-First Developer’s Toolkit

 

Swift continues to evolve with performance and safety at its core:

 

• Swift 6: Brings full support for ownership-based memory model (Rust-like safety)
• SwiftUI 4: Integrates animation, layout, and accessibility improvements
• VisionKit, RealityKit, HealthKit: Accelerated SDKs for domain-specific apps

 

Swift remains essential for:

 

• AR/VR (via Vision Pro)
• Health/Wellness Apps
• Payment + Authentication (Apple Pay, Face ID)

 

Rust + WebAssembly: Building Lightning-Fast Mobile Modules

 

Rust is not the main app language, but in 2025 it’s used extensively for:

 

• Cryptography
• Game engines (via Bevy Mobile)
• AI inference modules
• WASM components for hybrid apps

 

Benefits:

 

• Memory-safe concurrency
• No GC latency
• FFI-compatible with Dart, Kotlin, Swift
