Failure when generating Xcode project

When I generate the Xcode project with build support the build script hangs while the first target with name add_custom_target-… is build. The CPU usage eventually drops down to 0% as well and the build script seems to have reached a deadlock. Cancelling the script using Ctrl-C reveals that Python is indeed currently waiting for another process (see the attached command line output). The issue arises both when doing a clean build and limiting the number of parallel build jobs using --build-jobs 1.

Did anybody else encounter this issue or has an idea how to resolve it?

Ah, just figured out that the idea seems to be to build your Xcode project using --skip-build and run the ALL_BUILD scheme from inside Xcode. If that is the basic idea: Should I create a pull request to document it in the README or is the Xcode project with build support not really supported (because it isn’t mentioned in the current README)?
