An array of strings that represent macOS driver extensions that may communicate with other DriverKit services.
Discussion
Add this entitlement to your app that opens the IOUserClient. Set its value to an array of bundle IDs of driver extensions that you want to use with DriverKit. If you have only one bundle ID, you can use either a single string or a one-element array.
On iPadOS, use the Communicates with Drivers entitlement instead.
