The short answer
Choose React Native if you need iOS and Android from a small team on a tight timeline — most startups and MVPs. Choose Swiftif you’re iOS-only and lean heavily on cutting-edge native features (deep ARKit, complex widgets, maximum performance).
Side by side
| Prop | Type | Default | Description |
|---|---|---|---|
| Platforms | iOS + Android (one codebase) | iOS only | RN wins for reach |
| Language | JavaScript / TypeScript | Swift | RN reuses web talent |
| Performance | Near-native; great for most apps | Maximum native | Swift wins at the extreme |
| Time to ship | Fast — shared code, hot reload | Slower; one platform at a time | RN wins |
| Hiring | Large JS/RN pool | Smaller iOS-specialist pool | RN easier to staff |
| Native APIs | Most via libraries; bridge when needed | Full, day-one | Swift wins for brand-new APIs |
When React Native is the right call
You want both app stores, your team knows JavaScript/React, you’re shipping an MVP and iterating fast, and your app is mostly UI + data + standard device features (camera, push, location, payments). That describes the large majority of apps — which is why React Native (with Expo) is the default for founders in 2026.
When Swift is the right call
You’re iOS-only, you need the newest Apple frameworks the moment they ship, or you’re building something performance-critical (heavy graphics, real-time audio) where every millisecond counts. In those cases native pays off.
Gotchas
- “React Native is slow” is mostly outdated — the New Architecture closed most of the gap. For typical apps you won’t feel a difference.
- Swift means building (and maintaining) Android separately later. That’s a second codebase, not a port.
- React Native still needs occasional native code for niche features — budget for a bridge or a config plugin, not zero native work.
FAQ
Is React Native faster to build than Swift?Usually yes — one codebase for both platforms, hot reload, and a larger talent pool. Swift is faster only when you’re iOS-only and need bleeding-edge native APIs.
Can React Native match Swift performance? For the vast majority of apps, yes. Swift only pulls ahead in graphics-heavy or real-time workloads.
