React Native Error: Could not find iPhone X Simulator


error Could not find "iPhone X" simulator. Run CLI with --verbose flag for more details.
error Command failed with exit code 1.

In my case, the iPhone X Simulator wasn't installed.

I verified installed simulators before and after with:

xcrun simctl list devices


  • Open Xcode
  • Select Window > Devices and Simulators from the top menu bar
  • In the Devices and Simulators window, select the Simulators tab
  • Add the iPhone X (and any others) in the left sidebar
  • Don't give it a custom name since RN is looking for iPhone X
  • Click Create
