When I use your URL the JSON parsing works great, but other URLs like: http://bit.ly/1rA2jYI don't work.

This URL: http://ajax.googleapis.com/ajax/services/feed/load?v=2.0&q=http://rss.cnn.com/rss/edition.rss&num=20

Should allow me to pull CNN, and it comes up in the JSON Viewer chrome plugin so I know it is valid, but when I paste it in in xCode it doesn't work. I have been using the key: "entries"

If you take a closer look at the JSON that comes back from the feed link, you will notice that the root key is responseData which contains the key feed and then entries. So what you'll need to use is [@"responseData"][@"feed"][@"entries"] ( Screenshot here: https://www.dropbox.com/s/tks6tngyjme4o0c/Screenshot%202014-07-25%2011.39.55.png)

As to your question in the title about links from bit.ly, as well as other link shorteners for that matter, the actual call that you make is first to the shortener's server, which in turn will redirect your browser to the destination link. In the browser this works without you noticing anything but I believe in Xcode it will not work, you need to point Xcode to the real URL.

try the key "feed.entries"
