Founders do not need to become experts in React Native or Swift, but the choice can affect cost, timeline, and what the app can do later.
The right answer depends on the product. A simple habit app and a camera-heavy health product may need different technical choices.
Key takeaways
React Native is often faster for MVPs
React Native, often with Expo, can be a strong MVP choice because one codebase can support iOS now and potentially Android later.
Swift is best for deep iOS features
Swift can be the better choice when the app depends heavily on Apple's native APIs, advanced camera behavior, health data, widgets, or unusually complex performance needs.
What users notice
Users usually care less about the underlying technology than founders expect.
How to choose
Choose React Native when speed, budget, and possible cross-platform expansion matter.

It is especially useful for apps built around accounts, content, subscriptions, communities, dashboards, and standard mobile workflows.
Swift is best for deep iOS features
Swift can be the better choice when the app depends heavily on Apple's native APIs, advanced camera behavior, health data, widgets, or unusually complex performance needs.
The trade-off is that Swift is iOS-specific. If Android matters soon, that may mean a separate build later.
What users notice
Users usually care less about the underlying technology than founders expect. They care whether the app is fast, clear, stable, and useful.
A well-built React Native app is still a real app. A poorly scoped Swift app is still a poor product.
How to choose
Choose React Native when speed, budget, and possible cross-platform expansion matter. Choose Swift when deep iOS-specific behavior is central to the product.
Build with Kat can help choose the simplest technology path that gets version one into users' hands without overengineering the first release.
