Xcode 14.0 beta (14A5228q) refuses to build a DriverKit extension's installer app unless the dext's bundleID a single . suffix added to the bundling app's bundle ID. The error is
error build: Embedded binary's bundle identifier is not prefixed with the parent app's bundle identifier.
Is this behaviour intentional? Maybe it makes sense for non-driverkit bundled things, but it breaks existing software, invalidates existing dext bundle IDs and leads to awkward bundleIDs like com.foo.installer.mydriver.
