title: Why don't the WWDC 2010 video capture samples work in the Simulator?
body: <p>I downloaded the latest video capture samples from WWDC 2010 and am trying to run them in my simulator.</p>
  
  <p>Samples in general are supposed to run without any tinkering so I just unzipped a bunch of them and tried to run them in Xcode. None of the ones I tried runs.
  For example when I unzip and try to build findMyiCone I get 45 errors. </p>
  
  <p>Here are the first few lines</p>
  
  <pre><code>In file included from /Users/aw/Desktop/Sample code/WWDC10-SampleCode/FindMyiCone/Classes/ProcessViewController.h:49,

  </code></pre>
  
  <p>Im using Xcode 3.2.3 64 bit and have installed iPhone 4.0 SDK</p>
  
  <p>My other apps work fine.</p>
  
  <p>Anyone have similar issues? Any ideas what might be happening?</p>
