> http://trac.webkit.org/changeset/169765
> Change summary:
> Add -[WKWebView evaluateJavaScript:completionHandler:]
> Right now it's using the private method _runJavaScriptInFrame, in a category, and returns an empty string in the completionHandler.

> Steps to Reproduce:
> 1. Use WKWebView.
> 2. Try to evaluate JavaScript at an arbitrary time
> Expected Results:
> Ability evaluate JavaScript at an arbitrary time
> Actual Results:
> Not able to evaluate JavaScript at an arbitrary time
> Version:
> iOS 8 beta 2
> Configuration:
> iOS Simulator, iPad 2
