Is it currently possible to use the Local Authentication Framework in applications? as for example Open an application that saves data?
A different question, then.
From the docs:
"The
UIRequiredDeviceCapabilitiesInfo.plistThus, when asking if you can you restrict your app based on hardware alone, note there is no UIRequiredDeviceCapabilities key to restrict the app to devices with Touch ID.
As well, the HIGs.... say this about that:
"Face ID and Touch ID
Whenever possible, support biometric authentication. Face ID and Touch ID are secure, familiar authentication methods that people trust. If a user has enabled biometric authentication, you can assume they understand how it works, appreciate its convenience, and prefer to use it whenever possible. Bear in mind that people may choose to disable biometric authentication on their device, so your app should be prepared to handle this scenario."
Finally, section 5.1 in the ASRGs says that forced logins are best backed up with 'significant account-based features' - You haven't mentioned anything about accounts, so you seem at risk of pushback in that example.
It's used as a security layer for user authentication. What you do downstream of that process seems unrelated.

Are there certain issues related to it that you're needing help with?
