Know which user logging into app depending on touchid in iOS

Question

In my app I am trying to detect which user is trying to log in using touchId. Is there any mechanism which can help me distinguish between users depending on touch Ids of us

Answer 1

I assume that you are only assuming 1 one user per device since touch id isn't really setup for multiple users on a single device.

Since you already know which device your app is running on there would be no need to get this information from TouchID.
