title: NSPageController not allowed, but settings are set to OS X 10.8
body: <p>I am using an NSPageController in my app, in Targets -> Summary, Deployment Target is set to 10.8.</p>
  
  <p>In Targets -> Info, Minimum system version is <code>${MACOSX_DEPLOYMENT_TARGET}</code></p>
  
  <p>In Targets -> Build Settings, OS X Deployment Target is set to <code>OS X 10.8</code>.</p>
  
  <p>In Projects -> Info, OS X Deployment Target is set to <code>10.8</code>.</p>
  
  <p>In Projects -> Build Settings, Base SDK is set to <code>"Latest OS X (OS X 10.8)"</code>. Compiller is <code>Apple LLVM compiler 4.2</code>. And OS X Deployment Target says <code>OS X 10.8</code>.</p>
  
  <p>However, after doing all of this, when I try to build I get <code>"Class Unavailable: NSPageController on OS X versions prior to 10.8"</code></p>
  
  <p>Any ideas. I tried cleaning. I am on OS X 10.8.2, with the latest stable version of Xcode.</p>
