xcbuild is an Xcode-compatible build tool with the goal of providing faster builds, better documentation of the build process and running on multiple platforms (in particular OS X and Linux)

Why xcbuild?

xcbuild and other build tools

xctool Buck xcpretty
xcbuild and xctool are both Xcode-compatible build systems. We plan on slowly deprecating xctool's build support but keep it as a great way to run tests. Facebook's main build system is Buck. Buck has a stronger architecture and advanced features like artifact caching while having a much simpler build format. If you have a new project, it's highly recommended. xcbuild works great with xcpretty. Pipe the output from xcbuild to xcpretty the same way as you would from xcodebuild.


Build Status

  • Xcode 7 or later, on OS X.
  • GCC 4.8 or later, on Linux. libpng16-dev, zlib1g-dev, libxml2-dev, and pkg-config are also required.
  • CMake and Ninja (or llbuild).
    • With Homebrew: brew install cmake ninja
git clone https://github.com/facebook/xcbuild
cd xcbuild
git submodule update --init

Build output will be in the build directory. Run xcbuild with ./build/xcbuild.


The command line options are compatible with xcodebuild.

xcbuild -workspace Example.xcworkspace -scheme Example

Using Ninja (or llbuild)

To switch to the significantly faster Ninja executor:

xcbuild -executor ninja [-workspace Example.xcworkspace ...]

Besides the -executor ninja parameters, the options are otherwise identical. The Ninja executor is fastest if it can avoid re-generating the Ninja files if the build configuration and input project files do not change.
