SwiftQuick Recommendation
React Native
Best for Multi-PlatformChoose if you need:
- ✓You need both iOS and Android from a single codebase
- ✓Your team is JavaScript/TypeScript-first
- ✓Faster time-to-market outweighs iOS-specific polish
- ✓You want to share code with a React web application
Swift
Best for iOS-OnlyChoose if you need:
- ✓You are building an iOS-only app with no Android plans
- ✓Deep integration with Apple ecosystem (HealthKit, ARKit, Widgets, visionOS)
- ✓You need the absolute best iOS performance and UX
- ✓Your team has native iOS expertise
Side-by-Side Comparison
| Feature | React Native | Swift |
|---|---|---|
| Platforms | iOS + Android + Web | iOS, macOS, watchOS, visionOS |
| Language | TypeScript/JavaScript | Swift |
| UI Framework | React components -> native views | SwiftUI (declarative, native) |
| Performance | Near-native (JSI bridge) | Maximum native performance |
| App Size | ~8-15MB base | ~3-8MB base |
| Development Speed | Faster (one codebase for both) | Slower (iOS only) |
| Apple API Access | Via native modules (slight delay) | Immediate, day-one access |
| Hiring | Large JS pool, lower cost | Smaller pool, higher cost |
Our Verdict
If you need both iOS and Android, React Native is the clear winner -- building two apps with Swift and Kotlin costs roughly double. If you are building an iOS-only experience that deeply integrates with Apple's ecosystem (HealthKit, Widgets, visionOS, Apple Watch), Swift with SwiftUI delivers the best possible user experience. At Mendios, we use React Native for most client projects and recommend Swift only for iOS-exclusive apps with deep platform integration needs.
