Exciting things coming...
While my book, was written before Xcode 4 was even under NDA, and it seems like Xcode 3.x was just so old school, we are on the dawn of iOS 5 !
I am in the process of putting together examples of all the new things that are coming. In addition, I am planning to update all the applications in the book, to be iOS 5 compliant. The new source will be available soon after iOS 5 is publicly released.
My question to you is what format would you like these lessons to be in ?
Posts here in the forum, a blog, podcast ?
Let me know, these are exciting times !
