Summary
In this hour, you learned how to use the Xcode Source Editor for more than just typing text. We looked at special features like automatic code completion, auto-indentation, and code folding. You also learned how the Assistant Editor mode makes working on multiple related files a pain-free process.
In addition to the Source Editor itself, you explored the tools for identifying and correcting errors in your code, for searching and replacing text across your entire project, and for refactoring existing code. Although it is technically true that you can develop an application using any text editor you want, using Xcode gets you best-of-breed tools that are specific to the language and methodology of the Apple development platform.
