Another concern I have is once the tableview is working with AFNetworking 2.0, would I be having issues adding push notifications? (I'm thinking Parse PNs). Since I need to add their API to my project. Last year I gave up on AFNet because I had a problem with both using json callbacks.
I have created a fork with my changes.
They include both some stylistic changes and hopefully a fix in your parsing.
You should try thinking a little about your data structure, i.e. how you want to store events in memory.
Because your problem was caused by a mismatch in how your server structures events and how your client code parses it.
Let's compare the nesting in events2.json with your code.
events2.json: dictionary => array => dictionary
Your code: dictionary

Conference iPhone app: I'm thinking to show a list of events per day by pushing an action button (right arrow) reloading data on the same tableview(avoiding to segue to 4 new scenes). This app will eventually have more properties once the basic app gets going. Thanks for your feedback and corrections.
