White screen on iOS Safari in Vite React App (SWC + Vite 5) — works on desktop and Android

[Fenilsheta]

Describe the bug

I'm building a Vite + React + SWC project. Everything works fine on desktop (Chrome, Firefox, Edge) and Android browsers.
However, on iOS Safari (13-17), the app loads as a blank white screen, even though Vite HMR console logs show “connected”.

I tested it on multiple iPhones. No error in devtools (remote inspect), just a blank page. Even reducing component size and removing large files didn’t help.

Reproduction

Steps to reproduce

Start Vite dev server on LAN.

Open the app URL on iOS Safari or iOS Chrome.

App shows white screen despite Vite saying "connected".

Same build works fine on Android and desktop.
