I’m trying to support FaceID in my application.
LAContect().canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics, error: &error) returns true, so I expect that the device has biometrics enabled (which it has, it is an iPhone X with iOS 11.2.1 with FaceID enrolled and working for unlock).
So I expect to get
LABiometryType.typeTouchID when later checking
LAContext.biometryType, but as the title says it returns
Auctully, we need to first call
canEvaluatePolicy... in order to get the biometry type. That is, if you’re just doing
LAContext().biometryType then you’ll always get
none back. You would first need to call
canEvaluatePolicy... on that instance, and then
biometryType should have a non-none value (assuming the device has biometry support, and the user has enabled it).
