Presumably hot reload and IDE integrations that actually work. Xcode is really crappy compared to other IDEs, so platforms that can avoid it for most of your work tend to be an advantage. Xcode 26 generally broke anything that relies on indexing, like autocomplete, edit in scope, or refactoring, among others.

The npm ecosystem is one of the worst and most backwards places to be, so I don't think so.

- Hot reload that actually works.

- OTA updates, skipping Apple review for every little thing. Really speeds up builds too.

- Repack and module federation aren’t even possible on native

- running tests on iOS - 2 minutes minimum and having to boot the simulator in most cases. RN - seconds

- IDE with all sorts of plugins, that are impossible on Xcode, Rozenite

- AI trained on lots more React code, where they usually struggle to use Swift 6 properly

and a bunch more things

I assume all the extra work you have to do to make it work instead of using the native language.

If the project is simple to port over then it should have just been a website.
