Things I’ve done to figure out my issue

• [x] I used upgrade-helper to do my upgrade.

I recently upgraded my project from 0.73.11 to 0.78.0. I ran my app in debug mode in the iOS simulator(18.2). I see the metro bundle ran in my system. I pressed the j keyword to open the developer tools. The React-Native dev tools window is opened in my system but I cannot see the network inspector in the dev tool window. I used the flipper to debug and network inspector for my app in react-native:0.73.11

Upgrading version

0.78.0

Description

Reproducible demo

react-native run-ios --simulator "iPhone 16 Pro"

There is currently no way to inspect network traffic from RN with the new architecture. The Expo DevTools can do the work, however if you're ejected from Expo then the best you can do is copy and paste the code below into your App.tsx file before the component function declaration

const originalFetch = global.fetch;
global.fetch = async (...args) => {
  console.log('Fetching:', args);
  return originalFetch(...args);
};
if (global.HermesInternal?.enablePromiseRejectionTracker) {
  HermesInternal.enablePromiseRejectionTracker();
}

This will console.log the outgoing network requests, it's abysmal to say the least but it beats nothing.
