Lllustration by Elisabet Guba , Icons 8 from Ouch!Hello. I am Takahashi from the 1st Development Group.
I have been researching the iOS biometric authentication dialog and have compiled a summary of it.
Development environment
Swift5
Xcode 15.0.1
overview
I would like to share with you what I have learned about guadeloupe email address biometric authentication dialogs displayed using the Local Authentication
Framework. There wasn't much detailed information in the Apple Developer documentation, so this is a summary of what I found after tinkering around with it myself.

How to get started
If you want to use Face ID, add the following key and value to TARGETS > Info > Custom iOS Target Properties in your app project. In the value, describe the purpose (reason for using Face ID).Privacy - Face ID Usage Description

Types of Biometric Authentication
Currently, the following four biometric authentication types (Local Authentication > LAContext > LABiometryType) are defined.

none: Not available (device does not support biometric authentication)
Touch ID: Fingerprint authentication
Face ID: Facial recognition
Optic ID: Iris authentication
By the way, this time I only wanted to target Face ID/Touch ID that can be used on iPhone devices, so I defined and used the following enum.
