When a Touch ID enabled App is first run on iPhone X the user is asked if they want to use Face ID instead. If they decline then Face ID is disabled and the user is never again given the option to use the feature. Short of deleting and re-installing the App is there another way to enable Face ID?

The answer to this depends on whether you're running on actual iPhone X hardware or the iPhone X simulator.

On an actual device, the option is in Settings > Face ID & Passcode > Use Face ID For > Other Apps.

On the simulator, this option doesn't exist and your only option is Settings > General > Reset > Reset Location & Privacy.

From the Touch/Face ID docs:

"Bear in mind that people may choose to disable biometric authentication on their device, so your app should be prepared to handle this scenario.

....

Offer alternatives, like asking for a username and password, as fallbacks only if the initial method fails."

Isn't that setting treated the same way as all of the other settings--if the user wants to change their mind, they have to go to Settings on their own to do it?
