title: I'm getting compiler warnings with AFNetworking, but shouldn't be. How do I fix it?
body: <p>I'm using the most excellent <code>AFNetworking</code> library in a project that I'm currently upgrading to iOS 6. I'm in the middle of the upgrade, whittling down the bunch of warnings that I get when compiling against the iOS 6 SDK.</p>
  <h3>AFNetworking gives me two warnings in all targets:</h3>
  <pre><code>SystemConfiguration framework not found in project, or not included in
  precompiled header. Network reachability functionality will not be available.
  </code></pre>
  <p>and</p>
  <pre><code>MobileCoreServices framework not found in project, or not included in
  precompiled header. Automatic MIME type detection when uploading files
  in multipart requests will not be available.
  </code></pre>
  <p>Here's the thing, though: those two <code>libraries</code> <strong>are</strong> added in all my <code>targets</code>. I'd like to get rid of those warnings the proper way; I won't modify the <code>AFNetworking</code> files. I suspect it's Xcode being silly. It's admittedly a small thing, but leaving warnings around is bad practice.</p>
  <p>How can I remove those warnings?</p>
  <p>I've tried restarting Xcode and cleaning. Both don't work.</p>
