I am attempting to build a package for distribution. It is not clear how to fix the profile. Can someone point me some documentation that may help me resolve this?
Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile.

I have an app that is used to control features of a device with a driverkit driver. I am having trouble creating a connection a certain device.
The Sample code from "Communicating between a DriverKit extension and a client app.
The sample code shows:
ret = IOServiceGetMatchingServices(kIOMainPortDefault, IOServiceNameMatching(kDextIdentifier), &iterator);
I cannot use kDextIdentifier but need to find a service with a certain BSD Name. So in this case I try:
ret = IOServiceGetMatchingServices(kIOMainPortDefault, IOBSDNameMatching(kIOMasterPortDefault, NULL, interface), &iterator);
In each case the call completes correctly, and we get an iterator. I can also use IOServiceGetMatchingService with IOBSDNameMatching, and that completes correctly as well.
However when I attempt IOServiceOpen with the first case, the connection is created correctly. However, I have four of these in the machine, and I need to select the service and subsequently connection for a certain BSD name.
When I attempt the IOServiceOpen with the second/third calls, the IOServiceOpen call fails with error 0x2c7 which is unsupported.
Is there an entitlement I need to make this work?
