Are there any good tutorials for iPhone programming using Xcode 4 that cover more than the obvious "Hello World" example. Everything I found so far is either Xcode 3 or Hello World.
XCode is just the IDE. It may be a bit tricky if there are certain screenshots, but all in all the file structure is basically the same (Resources folder is now called Supporting Files), and the code is exactly the same - its still objective C, so all the tutorials that use XCode 3 should still be useful.
