title: Automatically adding generated source files to an xcode project
body: <p>I am using an IDL which automatically generates source files for my xcode project.  Does anyone know how I can automatically have the generated files added to the project?  Currently I have to delete the current files from the project and add the new ones.  This gets really annoying.</p>
  
  <p>Using a folder reference works for the header files but xcode doesn't want to recognize any files in a folder reference as source files.  Has anyone ever found a solution to this problem?</p>
