Test Face ID in the iOS Simulator from the command line
The Simulator's Features menu has three Face ID items: Enrolled, Matching Face and Non-matching Face. All three are notifications you can post with simctl, so a script can enroll a face, wait for the prompt and answer it. The one thing the simulator will not do is enforce biometric access control on a Keychain item.
