Building with Xcode

Building with Xcode

Before getting started, make sure you've installed all prerequisites for building Mapbox GL

To use Xcode, you'll first need to generate a project based on the CMake files. To do so, open a Terminal window, and run one of these commands from your checkout directory.

Run make xproj to create a project for building for macOS.
Run make iproj to create a project targeting iOS.
Run make qtproj to create a project targeting Qt.

This will generate the Xcode project files in distinct directories in the build folder. You can use these workspaces side by side. You should see output along these lines:

$ make xproj
mkdir -p build/macos
(cd build/macos && cmake -G Xcode ../..)

open platform/macos/macos.xcworkspace

On subsequent runs of make *proj, you'll see much shorter blurbs, or nothing at all (it'll just open the project in Xcode) when there were no changes in the CMake files.
