Cordova iOS Cross origin requests are only supported for HTTP -

i'm building ios app , upgraded cordova-ios 4.1.0 , started using: cordova-plugin-wkwebview-engine.

the problem error message cross origin requests supported http while trying load dependencies, app won't start.

it's trying load systemjs dependencies on file://, included in config.js.

i have no clue how fix this. have experience bevaviour?

cordova version: 6.1,0 cordova ios version: 4.1.0

related config.xml bit:

<access origin="*" /> <feature name="cdvwkwebviewengine">   <param name="ios-package" value="cdvwkwebviewengine" /> </feature>  <preference name="cordovawebviewengine" value="cdvwkwebviewengine" /> 

i had same issue cordova project (actually ionic v1) , fix following command:

cordova plugin add https://github.com/apache/cordova-plugins.git#wkwebview-engine-localhost 

this install webserver runs locally , error should gone after that. after run command, run:

cordova prepare ios 

or remove plugins , reinstall:

rm -rf plugins/ cordova platform add ios 

make sure have in config.xml:

<access origin="*" /> <feature name="cdvwkwebviewengine">   <param name="ios-package" value="cdvwkwebviewengine" /> </feature>  <preference name="cordovawebviewengine" value="cdvwkwebviewengine" />
