Ionic Capacitor IOS Only Works With Livereload

In my ionic capacitor ios app, the app works just fine on a web browser using ionic serve. When I try running ionic capacitor run ios, that is successful but when I build the app I get this:
While that looks like a lot, you can see that at the end it says Webview failed to load and the request timed out. On my phone, all I see is the splash screen.
Instead, when I run ionic cap run ios -l --external, I get this:
In this console, the same warning messages happen, but it says "onscript loading complete" and then the actual app works.
I have looked through many StackOverflow + github pages offering help for this issue. From this issue, I made sure that my phone and computer were on the same wifi. Anyone experienced this error before/knows what to do? This code has worked in the past.
I figured out the issue! The app was trying to connect to a server that did not exist. I needed to remove the server field in capacitor.config.json. I cut out that json field and then ran ionic cap run ios, and the code worked.
Please comment if you are still experiencing this issue

unexpected code 404 on publishing react native app on expo

I have been trying to publish my react-native app on expo so I can show it to others.
But i am facing error. I looked up on internet but couldn't find solution that can solve my problem.
The error is:
Building iOS bundle
Packager URL http://127.0.0.1:80/index.bundle?dev=false&minify=true&hot=false&platform=ios returned unexpected code 404. Please open your project in the Expo app and see if there are any errors. Also scroll up and make sure there were no errors or warnings when opening your project.
I am using visual studio code and when i run app by
expo start
It opens.. shows QR code... I scan with my iphone..and app opens in expo client.. works perfectly fine there but the above error comes when i try to publish.
can anyone tell me what might be the issue here please ?
Try to publish the app again unchecking the 'Optimize Assets' checkbox. This works for me.

Appcenter application pushing error form command line

I am working on Mobile app automation in VSTS using xamarin. Code was successfully executed on the local emulator, but while pushing to the appcenter from command line i am facing error Test Chunking failed.
I tried with admin privileges also, still i face issue can i know the solution.
Are there any further information? At the moment it sounds like the same problem that appeared at the official Xamarin forums.
https://forums.xamarin.com/discussion/68616/test-chunking-failed-format-of-the-executable-exe-or-library-dll-is-invalid
For me, what did the trick was to change the target framework of the Xamarin UI tests project to .Net Framework v4.6.1 (net461).

phonegap 3.0 console.log plugin http:localhost/!gap_exec 404 NOT FOUND

I've installed the console.log plugin "$ cordova plugin add org.apache.cordova.console" to my phonegap 3.0 project.
When I do console.log("xxx") in xcode, it work fine without any problem / error.
However when I test it in a web browser. The error "http:localhost/!gap_exec 404 NOT FOUND" appeared in the web browser console. When I comment out the console.log("xxx"), this error is disappear.
I just wonder whether it is really work fine in xcode. coz sometime xcode won't display javascript error.
Is there any debug tools for develop phonegap apps for ios / android?
Any cordova(phonegap) plugins is not for the web browser. when we install the console plugins it works on actual device because deviceready event fires but in case of web browser deviceready does not fire thus plugins are not working so, if you are doing so then please remove cordova.js file from your html and try in web-browser. but when you are ready with device include that file it is mandatory.
http:localhost/!gap_exec 404 NOT FOUND errors simply means that cordova(phonegap) does not find the actual device environment.

Sencha app with Cordova on Xcode

I am trying to build a ios package using sencha and phone gap. I followed the steps here http://vimeo.com/56673251. I am able to build and run the package on ios simulator. However, I can only see the index.html page. All the model, view and controller folders with js files created by sencha are not copied there. So, I am not able to run the app which i built using sencha.
When i click on the app/view/Main.js i get error The requested URL was not found on this server.
Any help on this would be great.
I think that the problem is that they expect you to run only the "production" version of you app inside cordova. When you set production the microloader is not used and everything is compiled into one file instead. That should solve the issue.
