title: iOS9 framework not found IOSurface
body: <p>When I use <code>IOSurface.framework</code>, the problem follows:</p>
  
  <pre><code>d: warning: directory not found for option '-F/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS9.3.sdk/System/Library/PrivateFrameworks' ld: framework not found IOSurface
  </code></pre>
  
  <p>I know IOSurface is a private framework and I just want to install the app into my iPhone, how to solve this problem?</p>
