Steven Degutis has started a site featuring video tutorials on Cocoa programming called Teach Me Cocoa. There’s one episode up so far covering Files and Collections.
I like the way Steven presents the material. Very good information presented in a thoughtful and simple way. Check out the site if you are interested in beginning Cocoa programming.
This is definitely going to be on my “must view” list as I start to gear up learning Cocoa programming again.
Steven has also started open sourcing some of the components he has written for the Mac. You can find his projects over on Git Hub.
