<p>I am receiving this warning in my debugger in xcode 8, iOS-10, when I using UIWebView Delegate methods to load something. I didn't find any documentation in Apple website about this web filter Active/De-active mode. Though it's not causing any problem in my existing webView functionality even I am running some javascript function in my webView did finished method. But still curious to know more about this new feature.  </p>

<p>Any suggestion about this feature will be appreciate.</p>
