[bug] IOS Whitescreen

[alexandre313412]

Describe the bug

Hi, I'm trying to run my app on my Mac for iOS, but I'm encountering a bug. On my iPhone, I see "error sending request for url". I tried the URL on Windows, Mac, and Android, and it works fine, but not on my iPhone (both Chrome and Safari).
When i put 0.0.0.0:1420 as devUrl, i have whitescreen

Reproduction

npm run tauri ios dev
npm run tauri ios build

Expected behavior

Is that with or without the --host flag. If you don't know that, or just didn't try it yet, please try npm run tauri ios dev -- --host
