Summary

When passing the --simulator flag with either the device name or udid it is ignored and the fallback is used

I believe it is the intended behaviour of the flag to launch with the id you specify but it was not being respected

Heres a video where i first use the current latest version without my change, then I link my local version of the cli and show it working

The udid i specify is for iphone17 so the first time when it launches the iphone16 thats just using the fallback

Test Plan

link to a local project and note that you can pick the simulator now

for example

yarn ios --simulator 'iPhone 17'
yarn ios --simulator '32D43F28-6167-488D-A94C-7F988698225A'
yarn ios --udid '32D43F28-6167-488D-A94C-7F988698225A'

Checklist

  • Documentation is up to date.
  • Follows commit message convention described in CONTRIBUTING.md.
  • For functional changes, my test plan has linked these CLI changes into a local react-native checkout (instructions).
