Hi!
I have a doubt. Is there a way to handle the errors if touch ID not matching? For example, if user tap on cancel button (in touch ID dialog).

Thanks!

In addition, I tried to handle the error getting NSData with the method dataForKey(key:promptMessage:error)
But I get a strange error when I pass error parameter (using swift):

let keychain = A0SimpleKeychain()
var keychainError: NSError?

// I get an error in error parameter: '&' used with non-inout argument of type '()'
let passwordData = keychain.dataForKey("some_key", promptMessage: "Some message", error: &keychainError)

Here the xcode suggested to delete '&'. But if I do it, the error appears: "Call can throw, but it is not marked with 'try' and the error is not handled"

Any suggestion?
Thank you!
