The document compares Xcode 3 and Xcode 4 to the JetBrains AppCode IDE, noting that Xcode 3 was unstable, lacked version control and unit test integration, and had poor refactoring. It then lists AppCode's features like smart code assistance, navigation, live analysis, Xcode support, refactoring tools, version control and issue tracker integration, unit testing, customizability, and plugins. It concludes by providing information on pricing AppCode at $99 for personal use or free for open source projects.
