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 (macOS, Linux, and Windows)

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.

Building xcbuild

Build Status


All platforms

On macOS you can install those tools with Homebrew: brew install cmake ninja.

On Windows you can install those tools with Chocolatey: choco install cmake ninja.


Ubuntu 18.04

sudo apt install libpng-dev libpng16-16 libxml2-dev pkg-config ninja-build

All others
  • GCC 4.8 or later. libpng16-dev, zlib1g-dev, libxml2-dev, and pkg-config are also required.


FreeBSD 12.1

pkg install png-1.6.37 libxml2-2.9.9 pkgconf-1.6.3,1 ninja-1.9.0,2 gmake-4.2.1_3


OpenBSD 6.6

pkg_add png-1.6.37 libxml-2.9.9 pkgconf-1.6.3 ninja-1.9.0 gmake-4.2.1p4


  • Xcode 7 or later.


  • Visual Studio 2015 or later, on Windows. A zlib DLL is also required.


All platforms

git clone --depth=1 https://github.com/facebook/xcbuild
cd xcbuild
git submodule update --init

Linux and macOS:


FreeBSD and OpenBSD:


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

You can place xcbuild in your bin directory to run it from other locations: mv build/xcbuild /usr/local/bin/.

Windows (experimental):

cmake -Bbuild -H. -G "Visual Studio 14 2015" -DZLIB_ROOT=<path>

Open build\xcbuild.sln and build.


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.
