title: ionic ios10 beta permissions bug
body: <p>I just upgraded to ios10 beta on my iPhone &amp; realized the permissions (to access photos, contacts, etc) now require a description string. I am on ionic 2</p>
  
  <p>I tried adding this: </p>
  
  <pre><code>&lt;config-file target="*-info.plist" parent="NSContactsUsageDescription"&gt;
  &lt;String&gt;This is my permission string&lt;/String&gt;
  &lt;/config-file&gt; 
  </code></pre>
  
  <p>to my config.xml but that did not work.</p>
  
  <p>I then tried to do it manually through XCode &amp; now it works but I have to put the app in the background in order to get the permission popup. Is this a known bug or is it something I'm doing wrong?</p>
