iOS 12 - Intents Extension - LocalAuthentication error

Hello,


I've been experiencing some weird issues in iOS 12 beta 5 and 6, but I don't think I saw them in beta 4.

From my Intents Extension, I was previously able to use LocalAuthentication to prompt a user for authentication when a Siri intent handler is triggered, similar to the example shown in this WWDC video: https://developer.apple.com/videos/play/wwdc2017/228/


On iOS 10 and 11, this method works great, but on the last two betas of iOS 12 that I've used (5 & 6), I've had issues.

I now receive the following error when trying to prompt the user for authentication during an Intent triggered by Siri:

Error Domain=com.apple.LocalAuthentication Code=-1004 "User interaction is required." UserInfo={NSLocalizedDescription=User interaction is required.}


Do I need to have a Intents UI Extension as well now, as of iOS 12, solely to use LocalAuthentication?


Thanks!
