Xcode offers many ways to find help. Most of those ways point to the same documentation set, but even the documentation pages help you submit suggestions for improvement. In addition, you will find a number of community Web sites (one of which is Apple-hosted) and blogs a quick Google search away. Even if the built-in documentation doesn’t help, the chances are quite good you’ll find your answer on the World Wide Web.
You should now have your bearings in the Xcode IDE. In Part II, you’ll use Xcode to expand on the TestApp project by adding some user interface elements, writing some code, defining a data model, and more. From there, you’ll delve into the debugger and building the application for deployment.
