Adding UIPreviewActionItem to SFSafariViewController might be a tedious task. This extansion should help.

let vc = SFSafariViewController(initialURL: url, entersReaderIfAvailable: true)
vc.previewActionItemsDelegate = self

When presenting SFSafariViewController use convenience initializer that will store original URL for later, it'll make custom action requiring original URL easier. But it's not mandatory.

Here is the delegate implementation, this is where we might want to use initialURL

func safariViewControllerPreviewActionItems(controller: SFSafariViewController) -> [UIPreviewActionItem] {

routes – an array of route objects
- request - configuration of a request.
  - method – a string according to RFC 2616.
  - pattern - a string to match, can be an escaped regex string. If regex is specified, it must match the entire request path.
- response - configuration of the response.
  - resourcePath - relative path of the resource to serve, if the request was matched.
  - contentType - optional an override for the resource content type. By default it's automatically deduced from the file MIME type.
