Building a React Native app that runs on your phone in development takes minutes. Shipping it to the App Store with auth, notifications, smooth animations, and solid performance takes weeks — not because any single piece is hard, but because the full picture spans six domains that no single tutorial covers end to end.

This is the guide we wish existed when we started building Appifex. It covers everything from file-based routing to App Store submission, with the actual code and the actual gotchas.

"Write once, run anywhere" has been a pitch since Java applets. React Native's version of it — one JavaScript codebase for iOS, Android, and web — is closer to reality than most attempts. But "closer" isn't "there." The asterisks matter.

We've shipped cross-platform React Native apps on Appifex that share 90%+ code across platforms. We've also seen projects where platform divergence crept up to 40%. The difference isn't the framework — it's what the app actually does.

We pushed a bug fix to a React Native app at 2pm on a Tuesday. By 2:01pm, every user who opened the app had the fix. No App Store submission. No review queue. No waiting.

Try that with a Swift app.
