title: Apple Mach-O Linker Error when using AVPlayers seekToTime:kCMTimeZero
body: <p>I get this error when trying to restart a movie clip.</p>
  
  <pre><code>Apple Mach-O Linker Error
  "_kCMTimeZero", referenced from:
  Linker command failed with the exit code 1 (use -v to see invocation)
  </code></pre>
  
  <p>I have looked at the build phase and it has <code>AVFoundation framework</code> included.</p>
  
  <p>Looked at other <code>Apple Mach-O Linker Error</code>, and which made me try doing a clean build, restarting XCode and the OS. But it didn't help.</p>
