Xcode 9 iOS 11 simulators Touch ID not working

I have turned on

Hardware > Touch ID > Enrolled
, but canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics:error:) is still returning
false
.

This issue only occurs on the iOS 11 simulators in Xcode 9 and works fine if I run an iOS 10 simulator from Xcode 9.

Does anyone know if this is a bug or why this might be happening?

Looks like this is a known issue as of Xcode 9 beta 4. See page 19 of the release notes.
