What worked for me was to open Xcode > Settings > Locations and make sure the Command Line Tools matched the version of Xcode I have installed.

Please note that due to ongoing issues with React Native and Xcode version 14.3 at least, you will most likely need to have another version of Xcode installed, and change the version of the Command Line Tools to either the version below, or the next version up. This will enable to you to build on the iOS simulator from your React Native project folder.
