Creating a hash or string via TouchID in Swift

Question

I want to create a unique string or hash via Touch ID on iPhone in Swift. I understand a lot about this, but I have not found a solution to do this.

Answer 1

You CANNOT do it.

you can use the universal unique identifier (UUID) of the ios device.

let uuid = NSUUID().UUIDString

or create your own unique identifier irreversible algorithms .
