Chapter 2: How Do I Get Started with Xcode?
Xcode is a powerful package with many features. You don’t need to master it all to get started, but you do need to have a basic understanding of its most obvious features. In addition to getting started with Xcode, you also need to start learning about iOS and the technical details of app design. You can find help for all these topics in Apple’s official documentation and in supporting unofficial documentation that can be yours for the price of a web search.
