title: Xcode 4.3.2 show hidden files
body: <p>I am using Xcode 4.3.2 and I am trying to add some SDK references to my project. 
  I can SEE the files using Finder, as I used the terminal script to view hidden files. 
  Yet, when I go to my user home directory in Xcode finder, it does not show the "hidden" 'Library' folder under my user profile that stores my SDK files. </p>
