I've got some admittedly old Objective-C code handling Keychain items protected by Touch ID / Face ID that uses the access control flag
kSecAccessControlTouchIDCurrentSet, accessing the items would fail with
errSecItemNotFound when the user adds or removes a finger/face from the device, however on iOS 15.0 this is not happening. It does work on iOS 14.6 still.
My deployment target is still iOS 11.0 so I haven't moved to
kSecAccessControlBiometryCurrentSet as the replacement for the now deprecated TouchID value - but the enum raw values are the same so I don't see how that could be the cause.
I can't see what the new error code is, because I'm not using Xcode 13, but I'll try and get the DeviceSupport copied in (official support for this is please!)
