Apple Xcode 4.1 final for OS X Lion. Xcode is as a complete, full-featured IDE built around a smooth workflow that integrates the editing of source code, with the build and compile steps, through to a graphical debugging experience - all without leaving the view of your source code. The IDE does more than these traditional tasks, however. With the advent of the iOS SDK, Xcode can now manage all your testing devices, automatically packaging iPhone apps with the proper certificates, and installing apps on the iPhone itself. The remote debugger connects to the device in real-time, managing breakpoints as the app is controlled on the device.
