This page gives you an overview how to develop multiple dependent Xcode projects at once.
Currently, it is not possible to build a workspace with the MiOS infrastructure. The projects must be built independently and deployed to Nexus. Therefore the explicit settings, required for the maven build must still be configured. When used together with the workspace, the explicit project settings are overwritten by the workspace handling. Therefore for local development scenario, using a workspace, the project resolution is done by the workspace settings and the maven builds using the settings, configured for the projects.
