title: SfSafariViewController and shared cookie storage
body: <p>SFSafariViewController(SVC) was introduced in iOS 9 and SVC can read cookies from Mobile safari  and not from the app and it can write cookies and it can be accessed by Mobile Safari and not mobile app.</p>
  
  <p>The above behaviour was same till iOS 10.</p>
  
  <p>Starting from iOS 11 SVC can't read cookies of Mobile Safari. </p>
  
  <p>So where are the things standing at cookie sharing as of iOS 11 ?</p>
  
  <p>Where SVC stores it's cookies from iOS 11 ?</p>
  
  <p>Does SVC store the cookie inside the launching app itself ?</p>
  
  <p>If yes , can webview(UIWebview/Wkwebview) in app read the cookies written by SVC</p>
  
  <p>If yes, can SVC read the cookies written by Webview</p>
  
  <p>If no , can SVC read the cookies that it wrote during the last session </p>
  
  <p>or SVC is more like incongnito version of Safari where it doesn't remember previous session and it can't access the cookies of both webview of the app and Mobile Safari. </p>
