- On iOS 11, Safari View Controller will have a separate persistent data store in each app
that it's used in.
- This means that cookies, local storage, and other browsing data will be contained within
your app and scoped to your app.
- And this means that the user won’t automatically be logged in to whatever accounts they
were logged into in Safari.
- What this does is it will prevent cross-app tracking of user’s browsing activity that you and
your users may not have even been aware about.
- And ultimately, it helps keep users’ browsing activity private and scoped within your app.

Manage cookies
Filter unwanted content
Provide custom resources

WKHTTPCookieStore
- Add and remove individual cookies
- Access all cookies visible to a WKWebView
- Including HTTP-only cookies
- Observe the cookie store for changes

WKContentRuleList
- Same syntax as Content Blocker extensions for Safari (JSON)
- Make content invisible
- Make insecure loads secure
- WebKit compiles your rules into efficient bytecode

WKURLSchemeHandler
- Allows your app to handle resource loads for a URL scheme
- Only custom URL schemes that WebKit doesn’t handle itself
- You cannot use “local” as your URL scheme

Load something in your view that uses your scheme

The WKURLSchemeTask sent to your handler represents a resource load
