stateHash

Contains state hash data for the available biometry type. Returns nil if no biometry entities are enrolled.

Declaration

var stateHash: Data? { get }

Discussion

If biometric database was modified (fingers, faces were removed or added), stateHash data will change. Nature of such database changes cannot be determined but comparing data of stateHash after different evaluatePolicy calls will reveal the fact database was changed between the calls.

     the state of biometry has not changed.
