in iOS 10 they changed "prefs:" to "App-Prefs:"

        guard let profileUrl = URL(string: "App-    
         Prefs:root=General") else {
            return
        }

         if UIApplication.shared.canOpenURL(profileUrl) {

         UIApplication.shared.open(profileUrl, completionHandler: { (success) in

            print(" Profile Settings opened: \(success)")

            })
         }
