Which language do you prefer to use while creating a new iOS App?

SwiftUI. My product 'Musium' was completed with SwiftUI, and it took less than a week to go online and publish it.

i like react-Native 50%

I think the ultimate win will be SwitfUI soon but for me now it is Swift.

Actually been using Capacitor & React (not Native)! The idea is basically that you develop primarily for web (where the dev ex is way better) and then it will compile to app native code for both iOS and Android. Definitely meant that there was much less to learn (since I have a purely React background)! I'm not sure yet if I fully recommend it because it can painful when trying to interact with device native APIs. Though that may be due to my own ignorance; I feel a little at the mercy of a few small community packages sometimes...

definitly react native, its the most easy to learn of all if you have web experience, takes almost no time to learn. The ultimate best is flutter, because it has the better performance and is also for both android and ios but i ha a hard time learning it, because dart is not that easy to understand at the beginning.

I used Nativescript the last time I developed a mobile app. Using Javascript. Really cool tool.
