This page gives you an overview how to enable Doxygen documentation generation for XCode Projects for Libraries.
API docs can be created and packaged with the maven-doxygen-plugin
together with the maven-assembly-plugin. In a first step the
maven-doxygen-plugin generates the api-doc. In a second step the
maven-assembly-plugin packages that documentation and attaches it as
side artifact.
Both plugins are preconfigured inside the xcode
parent pom file.
