So I've finally started the iOS5 Foundations section and produce the code myself, always better than just watching it and assuming I'm taking it in.
Automatic Reference Counting [DONE]
Storyboards [DONE]
Web View [DONE]
Core Data [DONE]
Notifications [In Progress]
Can't remember how much of iOS4 Foundations I completed but a lot has changed in Xcode since they were produced and others have found it hard to follow. Might go back and re-do at some point if needed.
There's a great community on the fb group if help is needed.
Just working on a pun app atm.
