ionic Failed to load webpage with error: Could not

I'm having an issue with Ionic projects after updating to Xcode 6 and iOS 8.

When trying to run projects I get the following error in Xcode:

Failed to load webpage with error: Could not connect to the server.

The full log is:

2014-10-11 14:08:29.468 test[23293:109668] Apache Cordova native platform version 3.6.3 is starting.

Even when trying to update Ionic and Cordova and starting a new project this error keeps popping up.

I couldn't find any threads with this particular error and I'm not sure if this is an iOS 8 compatibility issue or something is messed up with my setup.

Thanks!

EDIT:

A bit more info on what's in the index.html and app.js

index.html:

<!DOCTYPE html>
<html ng-app="app" ng-controller="AppCtrl">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

    <!-- compiled CSS -->
    <link rel="stylesheet" type="text/css" href="assets/app-0.0.1.css" />

    <!-- compiled JavaScript -->
    <script type="text/javascript" src="src/app/app.js"></script>

    <!-- cordova script (this will be a 404 during development) -->
    <script src="cordova.js"></script>
  </head>
  <body >
    <ion-nav-view></ion-nav-view>


    <!-- Load deferred scripts -->

    <!-- Google Maps -->
    <script src='http://maps.googleapis.com/maps/api/js?sensor=true&callback=googleMapsLoaded' defer async></script>
  </body>
</html>

and app.js (before compilation with the rest of the files using ngbp):

angular.module( 'app', [
  'ionic',

  // Common requirements
  'templates-app',
  'templates-common',

  // Common Components
  'app.auth',

  // All page modules
  'app.businesses',
  'app.business',
  'app.search',
  'app.branch',
  'app.profile',
  'app.feed',

  // Other dependencies
  'ui.router'
])

.config(['$stateProvider', '$urlRouterProvider', function myAppConfig ($stateProvider, $urlRouterProvider) {
  $stateProvider
  .state('app', {
    url: "/app",
    abstract: true,
    templateUrl: "menu/menu.tpl.html",
    controller: 'AppCtrl'
  });

  $urlRouterProvider.otherwise( 'app/feed' );
}])

.run(['$ionicPlatform', 'appAuthService', '$sessionStorage', function($ionicPlatform, appAuthService, $sessionStorage) {
  // Initialize ionic styles
  $ionicPlatform.ready(function() {
    if(window.StatusBar) {
      // org.apache.cordova.statusbar required
      StatusBar.styleDefault();
      StatusBar.styleLightContent();
    }
  });

  // Initialize app authentication service
  appAuthService.init();

  // Initialize a session cache validation object
  $sessionStorage.updated = {};
}])

.controller( 'AppCtrl', ['$scope', '$location', function AppCtrl ($scope, $location) {

}])

;

I had the same problem.

I opened the ios project in the platform folder via Xcode, but I forgot that the codebase in the Xcode folder was not up to date and therefore broken.

To get the new code in your Xcode project use the command:

ionic cordova prepare ios

If your problem is rooted in the same as mine this should help.

回答2:

This error may also occur if you open the project using Xcode after used the live debugging with the emulator

ionic cordova emulate ios --livereload -lc

To solve the issue, close Xcode and build the project again using

ionic cordova build ios

Then build and run using Xcode.

I had this same issue using XCode9.3 and ionic3. Turns out that the issue was caused by missing configurations in "config.xml" needed for WKWebview to function properly. I added the following snippet to my config.xml, before deleting the "platforms/ios" folder and running "ionic cordova build ios --prod" again.

 <allow-navigation href="http://localhost:8080/*" />
    <feature name="CDVWKWebViewEngine">
        <param name="ios-package" value="CDVWKWebViewEngine" />
    </feature>
    <preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

See link here for a more detailed explanation from the ionic team.
