I noticed that there are numerous missing source repositories. For instance:
Many files referenced in the xcodeproj are listed but do not actually exist in the repositories.
Right. This’s not uncommon. In general, the Darwin open source is meant to act as a general resource; in most cases it’s not set up to build the included projects.
If there’s something that you’d like to see added to the open source repository, you can reach out via the Contact link at the bottom of the main Apple Open Source page. Or you could open a request in Feedback Assistant.
Share and Enjoy
