@ch3tan03 After installing this, I am getting following error.

CDVWKWebViewEngine.h file not found

Any idea?

[DimitrisMpanis]

Should this be included in the official cordova wkwebview plug in?

Any update? I am also facing Could not signal service com.apple.WebKit.WebContent: 113: Could not find specified service in Simulator on iOS 11.0.1.

For iOS 13.0 there is CDVPlugin class WKWebViewXHRFix (pluginName: wkwebviewxhrfix) does not exist. but everything is working fine.

CDVWKWebViewEngine.h file not found

Also running cordova plugin add cordova-plugin-wkwebview-engine after cordova plugin add https://github.com/TheMattRay/cordova-plugin-wkwebviewxhrfix fixed this for me.

<plugin name="cordova-plugin-wkwebview-file-xhr"  source="npm" />

and add this

<preference name="WKWebViewOnly" value="true" />
<feature name="CDVWKWebViewEngine">
    <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>
<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

I have the same issue with cordova 10.0.0 ios platform 6.2.0 without using this plugin - see following issue:

https://stackoverflow.com/questions/67571345/ios-iphone-11-flashing-black-and-white-while-browsler-is-constantly-reloading-r

This plugin should not be used with cordova-iOS > 6, right? Any ideas how to fix this?

[breautek]

Correct, cordova-ios@6 implements the WKWebView itself as required by Apple's policies.

White page usually signals a javascript exception that has occurred. You can use the Safari web inspector (learn how) to check for javascript errors. Safari doesn't record errors that occurred before the inspector was attached, therefore you'll need to refresh the webview to see startup errors. You can do this by pressing cmd + R while the inspector is focused.

Cordova itself also doesn't do any kind of reloading on error, so this is likely behaviour coming from an external code, such as a framework, library, or perhaps even your own application.

@breautek Thanks for your reply. In the emulator there is no error so I see no log in the Safari Web Inspector. Is the inspector also accessible on real iOS devices? (I cannot test it at the moment because I currently have no Iphone 11 PRO available) - do I need that extra Safari Preview Browser?

You can use an inspector on physical devices, provided that the debug variant of the app is published on the device. This means the device will need to be added as a Test device on your developer account with Apple so that you can use XCode to build and install onto that device.

Sometimes the release version of Safari on the Mac is behind on the iOS Safari running on the device, particularly if you're using a recently released iOS version which may be incompatible for remote debugging. Usually in these cases, you can use Safari Tech Preview version of Safari to remote debug your webview.

There's no error in the safari console for iphone > about:blank or for iphone > [myappname]. about:blank is just an empty html page and [myappname] is the content of my cordova app, not the inappbrowser window.

[thomstark]

and i have cordova-plugin-wkwebviewxhrfix and have had for over a year now.
