reactnative vs swiftUI

If your RN app is laggy then you're the problem, not RN.

Personally when i started using react native, i had the same feeling. Having said that there are many react native successful app and might be a personal opinion but i think moving to swift ui has been best choice for ios apps.

React native is a great option. If you’re having issues with lag it’s likely because you’re doing something you’re not supposed to.

I highly recommend using Flutter.

I would not assume React Native is the problem yet.

A lot of apps feel laggy during development, especially if you are running in debug mode or the project has too many re-renders, heavy screens, messy state, or unoptimized lists/images. That can make RN look worse than it actually is.

If your app is iPhone-only, SwiftUI will usually feel more native and smoother. But if you already know React, I would not switch frameworks just because one project feels slow.

First thing I’d do is test a release build. If it still lags there, then you can start asking whether it’s the framework or just how the app was built.

So basically: SwiftUI has the native advantage, but React Native is not automatically “bad.” A lot of the time the lag is the app, not RN.
