The react-native run-ios --device command fails with an error. The app runs on the simulator using the react-native run-ios command without any problem. I suspect some misconfiguration in the XCode settings for this project. The versions involved are as follows:

XCode: 12.0.1.
iOS: 13.7 running on IPhone X
iOS Deployment Target Version: 12.0

The full error trace is as follows:

To run a react native app on an iOS device, you must run via the Xcode development environment on your selected iOS device connected to your development machine via USB.

react native can deploy and run on a connected Android device via the command line. This works well. The command line only supports running on iOS simulators unless something has changed.

See reactnative.dev site article “Running On Device”
