Ionic Core lnitiates inconsistently on real iOS device

I’m experiencing a problem that i can’t seem to figure out.

Whenever i run my ionic app on a real iOS device it sometimes works perfectly and sometimes freezes (after the splash screen hides). I’m suspecting that a plugin is failing to load causing the app to break.

Here are some details, hopefully there’s a problem with my coding:

Cordova CLI: 6.0.0
Ionic Version: 1.2.4-nightly-1917
Ionic CLI Version: 1.7.14
Ionic App Lib Version: 0.7.0
ios-deploy version: 1.8.4 
ios-sim version: 5.0.6 
OS: Mac OS X El Capitan
Node Version: v5.4.1
Xcode version: Xcode 7.2.1 Build version 7C1002

These are the plugins i’m currently using:

cordova-plugin-console 1.0.2 "Console"
cordova-plugin-device 1.1.0 "Device"
cordova-plugin-inappbrowser 1.3.0 "InAppBrowser"
cordova-plugin-splashscreen 3.2.0 "Splashscreen"
cordova-plugin-statusbar 2.1.1 "StatusBar"
cordova-plugin-whitelist 1.2.0 "Whitelist"
cordova-plugin-x-toast 2.4.0 "Toast"
ionic-plugin-keyboard 1.0.8 "Keyboard"
phonegap-plugin-push 1.5.3 "PushPlugin"

app.js file:

angular.module('starter', ['ionic','ionic.service.core', 
'starter.controllers', 'firebase', 'tagged.directives.autogrow', 'ui.calendar', 'ngCordova'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {

if (window.cordova && window.cordova.plugins.Keyboard) {

if (window.StatusBar) {
  // org.apache.cordova.statusbar required

var push = new Ionic.Push();

push.register(function(token) {
  console.log("Device token:",token.token);
  var tokenRef = new Firebase('');

  tokenRef.on('value', function(data){
    var exists = false;

            if (child.val().token == token.token){
              console.log('found match');
              exists = true;
              return true;

      if (exists === false){
        console.log('nothing found, add token');
        tokenRef.push({ "token": token.token });


.config(function($stateProvider, $urlRouterProvider, $ionicConfigProvider) {
if (ionic.Platform.isIOS()){


.state('app', {
url: '/app',
abstract: true,
templateUrl: 'templates/menu.html',
controller: 'AppCtrl'

.state('app.contacts', {
url: '/contacts',
views: {
  'menuContent': {
    templateUrl: 'templates/contacts.html',
			controller: 'ContactsCtrl'

etc etc .......

Thank you.

Be sure to wrap all plugin calls in a Device Ready. If you dont and the app is not ready when calling a plugin the app stops.

It is, please check the app.js file or highlight what should change.

I dont see problems. Did you tested the app in a browser (chrome)?
Did you look the console message in the browser debug window??
Can you show me a dump of the console messages?

Anoither issue I once had. Sometimes the emulator is messed up. Firs in the menu of the IOS simulator klik on reset. This takes a few seconds. No run the app in xcode again.

Hi thanks for your response.

Yes it’s been tested and developed on chrome. No errors in the console log. It works every time on there and it also works every time on the emulator, my issue isn’t in that. I believe it works because Ionic native push notifications can’t be used in chrome or ios emulator. Ionic push debug mode is working successfully on chrome.

My issue is running it on a real iOS device, if the app works, everything works (including native push notifications), otherwise it freezes after the splashscreen has loaded.

Looking at the console messages posted above I notice Ionic Core isn’t initiating.

Maybe there’s a bug in that?

I have an app with all of it running. Native Ionic Push notifications, Ionic Deploy, Ionic analytics etc.
If I start the app in xcode I see a message that native Pushnotifications not working in the simulator.
But if a run the app on a real device iPad or iPhone from xcode Pushnotification is regeistered etc. On a real device this works.
My experience is that if the app stops most of the time it is because the app is trying to call a plugin before deviceReady. Try to find out how far your app is running by inserting console.log messages. Look in Chrome console what is the last message before the app stops.

I agree, that’s what i think too. I’ll see if i can narrow down the problem. Also i’ve seen other posts mentioning Ionic Core and Firebase get into a bit of a cat fight when the app runs. wrapping the firebase calls in device ready has stabilised the app a bit more, but it still hasn’t solved the app from randomly freezing. For the time being i just have to live with it until i’ve found a solution.

Hey, i had the same problem and followed your thread. After reading the following changes fixed it for me.

Thank you. I’ll give it a try. I’m guessing this might get fixed in the next cordova ios release?

Thank you. The new Cordova iOS 4.1.0 fixed the issue for me.

I took the following steps:

sudo npm update -g cordova ionic
rm -rf plugins
rm -rf platforms
ionic hooks add
ionic platform add ios@4.1.0
ionic build ios
cordova prepare
