This is an old question, so I hope you've resolved it, but if not or for future readers, I found a solution in this GH thread https://github.com/facebook/react-native/issues/29587

I uninstalled watchman with brew uninstall watchman (and did not reinstall it) and my iOS app was able to connect! Tried several solutions and this is the only one that worked for me.

I tried multiple solutions for the above issue.

  1. rm -rf node_modules/ && rm -rf yarn_lock/ && yarn install && cd ios && pod install
  2. checking out the specific process & cancel thatthread/process by specifying the p_id nmp
  3. audit --fix

None of the above solution worked for me except this command enter image description here

After all you have to do yarn add react-native-gesture-handler react-native-reanimated react-native-screens

Close bundler & shift +cmd + k on xcode and run the app by cmd + R

I had the same issue, tried a lot but the solution is really simple. Just hit the 'i' key from the terminal and the connection occurs just fine.
