title: In-app AJAX not working in iOS with Cordova 10
body: <p>I just updated from Cordova 8 to Cordova 10. Mainly because of Apple deprecating UIWebView. I use cordova-ios@6.1.1. I create a default Cordova project for test purposes. I add no plugins, no other stuff except jQuery version 3.5.1. I add AJAX request to internal application file css/index.css ( this works fine in Cordova 8 ):</p>
  <pre><code>function onDeviceReady() {
      // Cordova is now initialized. Have fun!
  
      console.log('Running cordova-' + cordova.platformId + '@' + cordova.version);
      document.getElementById('deviceready').classList.add('ready');
  
      $.ajax({
          url: &quot;css/index.css&quot;,
          success: function (resp) {
              console.log(&quot;load OK&quot;);
              return false;
          },
          error: function (xhr, status, exc) {
              console.log(&quot;load fail&quot;);
              return false;
          }
      });
  }
  </code></pre>
  <p>When I run the application, the AJAX call fails with status = &quot;error&quot;. Please, could anybody advice what was changed and how to make such an AJAX calls working?</p>
