How long do you think it will take? Sisyphus
Guys from apache cordova are working hard on workaround for the bug, because they say that a chance that apple announce a bugfix equals to 0,0001, there are many other bugs in WKWebView, they are trying to workaround them too, but it's not easy, to introduce updated cordova they need to be sure that EVERYTHING is fixed and working without problems, this will take time...
As for apple, this WKWebView bug first encountered in ios 8 beta 4, it's still not fixed in ios 8.2 beta 4, half of year passed, still no fix, so nobody waiting for a fix now, even guys from apache.
You can use Ludei's Webview+, it's a WKWebView with workarounds, working very well, sometimes dissapointing with bugs like clearing the local storage on low memory, but it's the best export option for ios.
