Ios, building but not running on simulator


Hi, I’m trying to run my app on an iOS simulator from xcode and cli.

It builds & stays stuck on the splash screen.
On android, it builds & run well on any device… I just don’t have an iOS device yet.

Google around the error below, it may point toward a file:// issue, but I don’t have any in my code.
Looking at the link in the log below, it may be induced by the simulation…

Did you remote debug the problem on the device already? Follow these instructions here to debug the problem in Safari dev tools: Look at the console and network tabs for errors.


Hi thanks for the reply.

On a real device, I’m not getting the error, but it’s stuck on splash screen too though.

In the console I only see

[Debug] Ionic Stop Scroll injected! (user-script:1, line 50)

In the network I only see index.html which it not loaded, 404.

URL: ionic://localhost/var/mobile/Containers/Data/Application/AC3A00A8-21CA-42C6-9344-401938A8E4A9/Library/Application%20Support/8fa64ebd-79c4-4c07-aa58-18c66399b1ea/index.html?cordova_js_bootstrap_resource=/var/containers/Bundle/Application/FDBADB93-295B-4D96-8866-5D352A4CA0B1/

Here I lack knowledge to understand why the 404 would occur. Is there anything I should specify for the build to copy data over to the phone?

If I add
<script src="cordova.js"></script>
I’m not getting the 404 but the app is still stuck on the splash screen and I get no console or network traffic from safari, in the localhost context…

Please note, the first time I ran on the device, it downloaded & unzipped to the phone, then got stuck.
I stopped the app from xcode and ran it again. That’s where I am now, but I cannot see a download & extraction of a zip file to the phone…

Thanks for your help


Create a new Ionic project and see if you can build and run that one.


Hi, after a bit of a struggle, I realised there was a config in XCode that specified to either use Cordova lib or Porject lib to build… it was set to Project and using Cordova it built & ran successfully on the device.
