same for me

[elrabelo]

I just forgot to add this to my config.xml. Sorry for that.
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

All changes in config.xml.

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

<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

[elrabelo]

To soon saying that..
It worked, now it's not working anymore and I didn't do anything...
Reopening issue...

[gbelmm]

+1 please

[manucorporat]

1. Clean install:

rm -rf platforms
rm -rf plugins

2. Recreate cordova

cordova platform add ios

3. Make sure localhost is allowed:

<allow-navigation href="http://localhost:8080/*"/>

4. Make sure WKWebView is the default engine:

<feature name="CDVWKWebViewEngine">
  <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>

<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

5. Build ios

ionic build ios

did it work?

[kleeb]

localhost:8080 ?
does it mean you added a localhost server that is running na natives?

this will bring all the CORS problem to the iOS

[stansongman]

I am having the same problem. I did the clean re-install, and It is still happening. All loads well until here BUT, If I untether the phone and start the up, it comes up fine.

[VERBOSE] [::1:8080] ::1:52428 200 "GET /var/containers/Bundle/Application/03B2DC93-ACE3-419C-8F35-8AC8D594770E/MyApp.app/www/templates/signIn.html" (565 | 2024)
MyApp(651,0x1b5d10c40) malloc: *** error for object 0x1700af180: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
(lldb)

If I continue, the app crashes right after my signin view is rendered, UNLESS the phone is untethered.

Also seeing this issue. It used to work and then suddenly the app doesn't load anymore.

[stansongman]

Update: I found this on StackOverflow
which solved the issue for me.

@kleeb I think there is a way to proxy the calls but I have no idea how we should do this now.

[JiaLiPassion]

@kleeb, @epetre , I have created a PR #115 to add a local proxy server to proxy all xhr request. maybe it can fulfill your requests.

[kleeb]

Wow. Thanks @JiaLiPassion
Looks really interesting and we will definitely take a look at it.

[epetre]

I'm running on the webview engine now and it works well.

It looks like its a safari bug and therefore only appears when you are debugging your webview with safari. In Safari under Develop->Your_Device_Name uncheck "Automatically Show Web Inspector for JSContexts". This should resolve your issue.
