In case you haven’t already watched them, I suggest checking out the Xcode 4 video tutorials published by The Pragmatic Studio. Each of them is short and to the point, and free! Even though I have been using Xcode 4 since it was released, these videos had plenty of useful tips and tricks for me.
After watching some of their free videos about Xcode 4, I invested in the six-part video series about Core Animation: Creating a Compelling User Interface with Core Animation. I’m really excited to watch that series!
