title: IOKit Not found
body: <p>So everything was fine, and then I decided to start developing on XCode 5 DP3 and iOS7</p>
  
  <p>Prior to upgrading, my project compiled and ran fine on my iPhone 3GS (I made a little soft phone application); it didn't run on my iPhone 5, however; I was very confident that it was the fact that I hadn't configured it to include the armv7s architecture yet. </p>
  
  <p>I can build and run everything just fine on the simulators, but (and this is after configuring the app to include the armv7s architecture) I can't get it to run on either my devices.</p>
  
  <p>I get this error:</p>
  
  <pre><code>ld: framework not found IOKit
  clang: error: linker command failed with exit code 1 (use -v to see invocation)
  </code></pre>
  
  <p>I'm not even sure how one uses -v to see invocation. 
  I read some where that IOKit is just for the simulator... does this mean that I should unlink it from my library when building on my device? And why wasn't I getting this error before when it was working on my 3gs?</p>
  
  <p>My assumption for why it no longer works on my 3gs (although the error is the same), is the fact that it's iOS 6, and the SDK may only support iOS 7 (which my iPhone 5 currently is). </p>
