When I simulate Face id mismatch, the error thrown is

Error Domain=com.apple.LocalAuthentication Code=-10 "Lost connection to coreauthd." UserInfo={NSLocalizedDescription=Lost connection to coreauthd.}

Should it not be LAErrorAuthenticationFailed?

I'm also getting this, but for a Face ID match.

It seems like there's a bug with the simulator that makes it fail with this error every couple of tries.

Here's a video of what I was seeing: https://youtu.be/4GyaOymoHN0

  I got the same error:
  Lost connection to coreauthd.
  on XCode 9.01 or XCode 9.1 beta.

Same here! Hope they fix this before launch day so we can validate our login flow.

I think it does it on every second FaceID attempt. I can repeat it consistently. It looks like it's been fixed in the full Xcode 9.1 release. Testing with a simple local auth attempt works consistently now.
