I noticed last night that Xcode now has a WKWebView Object in the Object Library Selection.
This had been missing in action for a while and you had to manually create one.
The WKWebView also has a few controls in the Attributes inspector.
You can a add them to your views and connect them in the normal way as you would with any view.
The old UIWebView is also marked as depreciated.
(sorry I cannot put up any images at the mo… )
