xcbuild

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

• Xcode 7 or later, on macOS.
• GCC 4.8 or later, on Linux. libpng16-dev, zlib1g-dev, libxml2-dev, and pkg-config are also required.
• Visual Studio 2015 or later, on Windows. A zlib DLL is also required.
• CMake and Ninja (or llbuild).
  • With Homebrew: brew install cmake ninja
  • With Chocolatey: choco install cmake ninja

To build:

• All platforms:

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

• Linux and macOS:

make

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

• Windows (experimental):

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

Open build\xcbuild.sln and build.

Usage

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.
