iOS: Setting cloudSync: false causes unexpected error with ACCESS_CONTROL.BIOMETRY_ANY_OR_DEVICE_PASSCODE

[jacksondoherty]

My impression is that cloudSync: true forces Keychain to use a less secure encryption method to sync with iCloud, so that would make sense that it would not be compatible with ACCESS_CONTROL.BIOMETRY_ANY_OR_DEVICE_PASSCODE. But I'm actually setting cloudSync: false, (which I imagine should be its default value). The error I receive is:

Error: One or more parameters passed to a function where not valid.

Is this a bug or can I get some sort of explanation here?
