title: LSApplicationQueriesSchemes and derived data
body: <p>I would like to open a whatsapp url in my app like.</p>
  
  <pre><code>let whatsAppUrl = NSURL(string: "whatsapp://send?text=Hello%2C%20World!")
  if UIApplication.sharedApplication().canOpenURL(whatsAppUrl!) {
      UIApplication.sharedApplication().openURL(whatsAppUrl!)
  }
  </code></pre>
  
  <p>I extend my info.plist with a dictionary "LSApplicationQueriesSchemes" and add my url scheme for whatsapp.</p>
  
  <pre><code>&lt;key&gt;LSApplicationQueriesSchemes&lt;/key&gt;
  &lt;dict&gt;
      &lt;key&gt;Item 0&lt;/key&gt;
      &lt;string&gt;whatsapp&lt;/string&gt;
  &lt;/dict&gt;
  </code></pre>
  
  <p>If i run my app i get the following error message.</p>
  
  <pre><code>"This app is not allowed to query for scheme whatsapp"
  </code></pre>
  
  <p>I read some solutions with cleaning the derived data and run the app again to fix this issue. But this not help me, exists an other solution for my issue?</p>
