Hi, I just pushed an experimental branch with the Buck build for you to try out. It works for macOS, Linux and FreeBSD. Windows isn't included yet.

Will I be able to build and debug in Xcode? This is possible with current CMake system.

Buck has the functionality but I didn't test it myself yet because I don't use xcode. If you want to give it a try checkout https://buckbuild.com/command/project.html

$ buck project --ide Xcode osquery:osqueryd Generating project: finished in 0.2 sec //osquery:osqueryd must be a xcode_workspace_config, apple_binary, apple_bundle, or apple_library
