SimpleViewer is an off-shoot of my Helium 3 project on github. I figured there may be others wading into the new WkWebView area and would apperciate a starting point - I would.
Anyway, similar to Helium, SimpleViewer is intended to be a simple viewer of web pages, documents, etc supported by Apple's new WkWebView App kit framework.
It supports Apple's sandbox, drag-n-drop, and file open. Being a viewer, it does not explicitly write out user's files etc, but being a document based app, will remember documents last seen.
This is a working prototype, aka some things do not work - ie.. auto layout, but I plan to address these issues once I figure out how, or learn from others.
So enjoy.
