React Native vs Swift
One codebase covering both platforms, or a native iOS app tuned for peak performance? Here's how we'd decide.
Get expert adviceCross-Platform vs Native iOS
React Native gives you iOS and Android apps from a single JavaScript codebase. Swift is Apple's own language, built for iOS apps that need maximum performance and platform fidelity. They aren't direct equals — one is cross-platform, the other is iOS-only.
What usually settles it: do you need Android too, how performance-critical is the app, and how deep do you have to go into Apple's newest features? The trade-offs below are the honest ones.

ISO 9001:2015 CertifiedReact Native at a Glance
Language
JavaScript/TypeScript — web teams already know it, the talent pool is huge, and one build targets iOS and Android together.
Performance
Good enough for most apps, and the New Architecture keeps closing the gap to native. Really demanding UIs may still want native modules.
UI
It renders actual native components for a genuine platform feel, with native-module escape hatches when needed.
Ecosystem
The npm ecosystem is enormous, you can share code with React web apps, and a single codebase covers both platforms.
Swift at a Glance
Language
Swift plus SwiftUI/UIKit — Apple's own first-party tools for polished iOS (and wider Apple ecosystem) apps.
Performance
Nothing beats it on iOS. Direct hardware access, no abstraction layer in the way — the right call for demanding apps.
UI
Apple's design conventions, pixel-perfect, plus day-one access to whatever iOS features and APIs ship next.
Ecosystem
First-class Apple tooling and frameworks, deep ones. But it's iOS-only, so Android means a separate Kotlin app.
When to Choose Which
Pick React Native if you need both iOS and Android from one team and codebase, or you want to reuse React/web skills.
Pick Swift if you are iOS-only and need peak performance, deep hardware integration, or day-one access to new Apple features.
Pick React Native for faster, budget-friendly multi-platform launches; pick Swift for premium, performance-defining iOS experiences.
Consider a hybrid
a React Native core, with Swift native modules handling the handful of performance-critical screens.
Our Recommendation
If you need Android as well, React Native almost always wins on cost and speed for a single shared codebase.
For iOS-only apps where performance, polish, or cutting-edge Apple features are the product, we recommend Swift.
Tell us your platform targets and performance needs, and we'll recommend React Native, Swift, or a hybrid.

Frequently Asked Questions
Is Swift faster than React Native?
On iOS, yes — Swift is native with no abstraction layer, and that edge matters for demanding apps. For a typical business app, though, React Native performs well enough that the difference rarely decides anything.
Can React Native build for Android too?
Yes, and that's the whole point. One React Native codebase ships to both iOS and Android. Swift stays iOS-only, so covering Android would mean writing a separate Kotlin app.
Which is more cost-effective?
If you need both platforms, React Native usually costs less — one team, one codebase, one thing to maintain. Swift can be the efficient choice when you're iOS-only and need native depth.
Can I combine Swift with React Native?
Yes. A pattern we use often: build the app in React Native, then write Swift native modules for the few performance-critical or platform-specific features. You keep shared code and still get native power.
