Change WebView to WKWebView to give more clarity in the log here.
> The webView should reload when a crash occurs (iOS 8)

> Key: CB-11997
> URL: https://issues.apache.org/jira/browse/CB-11997
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin WKWebViewEngine
> Reporter: Connor Pearson
> Assignee: Shazron Abdullah
>
> When the WKProcess dies, the content is blanked out and the URL becomes nil.
> This results in a "white screen" that can only be resolved by restarting the
> app. See this for more info: https://bugs.webkit.org/show_bug.cgi?id=148685
> With the iOS9 API, it is now possible to detect when the WKProcess dies. On
> iOS 8, we can listen for changes on URL of the WKWebView to be notified when
> it crashes.
