Xcode 4 provides a more intuitive integrated development environment with a single window interface, easier navigation and debugging tools, and tighter integration with source control and other development workflows. Key features include syntax checking, side-by-side editing of source code and headers, a jump bar for quick navigation, and built-in version control integration. The single window approach and assistant pane create a more unified and streamlined coding experience.
