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

Question

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 l         


        

Answer 1

I encountered this issue when I tried to run my Ionic 4 app on an iOS device.

What solved it for me, was running the dev server on all network interfaces using the --address option, for example:

ionic cordova run ios --address=0.0.0.0 --debug --consolelogs -l

Answer 2

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" />
