What is XCBBuildService / SWBBuildService on Mac?
By Junaid, maker of Taskglass · Last reviewed
Xcode's build system service, which plans and runs your project's builds.
XCBBuildService is the service that runs Xcode's build system; newer toolchains include SWBBuildService, from Apple's open-source Swift Build. It works out what needs to be compiled and launches the compilers and other tools. It's active while building or while Xcode prepares build information for indexing.
