body: <p>Hello fellow developers,</p>
  <p>I'm uploading an app with share extension, extension should only accept images.</p>
  <p>For some reason when I'm uploading app for beta testing i get an warning as  below.</p>
  <blockquote>
  <p>No values under NSExtensionActivationRule in bundle APPNAME.app/PlugIns/ShareOnAPPNAME.appex appear to trigger activation.</p>
  </blockquote>
  <p>Also I got email saying below</p>
  <blockquote>
  <p>Dear developer,</p>
  <p>We have discovered one or more issues with your recent delivery for &quot;APPNAME&quot;. Your delivery was successful, but you may wish to correct the following issues in your next delivery:</p>
  <p>Unreachable Activation - No values under NSExtensionActivationRule in bundle APPNAME.app/PlugIns/ShareOnAPPNAME.appex appear to trigger activation.</p>

  <p>My plist file in extension target looks like this...I tried adding all support key with value 0 except image and only image key with value 1...but warning persists...</p>
  <pre><code>&lt;key&gt;NSExtension&lt;/key&gt;
  &lt;dict&gt;
      &lt;key&gt;NSExtensionAttributes&lt;/key&gt;
      &lt;dict&gt;
          &lt;key&gt;NSExtensionActivationRule&lt;/key&gt;
          &lt;dict&gt;
              &lt;key&gt; NSExtensionActivationSupportsImageWithMaxCount &lt;/key&gt;
              &lt;integer&gt;1&lt;/integer&gt;
              &lt;key&gt;NSExtensionActivationSupportsText&lt;/key&gt;
              &lt;false/&gt;
          &lt;/dict&gt;
      &lt;/dict&gt;
      &lt;key&gt;NSExtensionPointIdentifier&lt;/key&gt;
      &lt;string&gt;com.apple.share-services&lt;/string&gt;
      &lt;key&gt;NSExtensionPrincipalClass&lt;/key&gt;
      &lt;string&gt;ShareOnAPPNAMEVC&lt;/string&gt;
  &lt;/dict&gt;

  <p>Also App shows sharing option to each and every type i.e. movies, text, webpage etc. along with images.</p>
