title: Xcode does not pick up new class files in SVN
body: <p>I have an SVN repository that I have updated my local code from, and this update included new class files. When I went to build, there was a linker error due to the fact that code in my files that were previously in Xcode had been updated and referenced a new file. this file has been added to my directory in Finder (i.e. my local filesystem is up to date) but these new files have not been added to my xcode.</p>
  
  <p>My question is: how do new files become found by Xcode?? or which metadata file stores the files that show up in the right hand pane in Xcode? (so I can check if this is updated or not)</p>
