title: Does WKWebView implement parental control?
body: <p>I have a simple WKWebView browser in my app. I happened to test it on an iOS 9.1 phone with parental controls turned on in - Settings - General - Restrictions. In testing (honest) I happened to click a link to an adult site. I saw</p>
  
  <blockquote>
    <p>You cannot browse this page at [URL] because it is restricted.</p>
  </blockquote>
  
  <p>I wasn't aware that WKWebView implemented Apple parental controls. It's handy if it does, avoiding age restriction problems in the store. Is what I have seen the parental control operating? Is there an Apple document somewhere that says that WKWebView implements parental controls?</p>
  
  <p>I had to both turn on <code>Settings - General - Restrictions</code> and also set <code>Websites - Limit Adult Content</code> to see this behaviour. When I did that, I also saw this behaviour on an iOS 9.2 iPad.</p>
