title: WKWebView autocomplete suggestions in UITextField
body: <p>I am using a WKWebview to display web page and have a UITextField where the user can enter the URL they wish to navigate to (in-app browser of sorts). As the user is typing, I would like to display a list of possibilities (i.e. popular sites). Are there any Apple (or 3rd party) APIs I could use to fetch a list of popular sites based on a substring? </p>
  
  <p>Edit: I need to use a WKWebView as opposed to the new Safari View Controller because I want to be able to inject custom javascript (which is not allowed in the former)</p>
