I have XCode 15.0 project with dext target (C++).
Including of <memory>, <vector> and some other headers causes compilation error: __debug file not found.
Base SDK and Supported platforms: DriverKit.
But there are no such problems for other C++ targets inside the project - command line tools, etc.
I know there are some restrictions for system extensions - direct file access, interprocess communication,
but this problem looks like a bug, or misconfiguration of my system.
Reinstallation of XCode didn't help, as well as __debug file copy to DriverKit framework headers folder.
The problem was solved by adding a link to __debug file into the list of project sources. May be not portable solution for different SDK versions, but working.
