BFTouchID error after ios10.0

[AbooJan]

after iOS 10.0，when I call showTouchID function, it will callback systemCancel error first。

I set the breakpoint and see the error. when call context.evaluatePolicy , system will show the touchID alert, and then this function will callback systemCancel error first. After I auth the touchID, it callback success.

this error can not see in ios 9.0 。

some one know why

I'm sorry but I can't reproduce your bug.
Everything works fine on my iPhone X, even with Face ID.
Can you give me more details?

My device is iPhone 7. iOS 11.1.2

here is the step:

1. call showTouchID function
2. app show the touchID alert
3. function callback systemCancel error
4. My finger touch iPhone to verify touchID
5. function callback success result

you will see the showTouchID function callback twice.
but my expectation is callback once

I made a complete rewrite of the biometric auth with a new Struct BFBiometric.
Can you try the feature/biometric branch, please?
