Xcode is an integrated development environment (IDE) created by Apple for developing software on its platforms, including iOS, macOS, watchOS, and tvOS. It provides developers with tools to write, debug, and compile code, making it easier to create applications for Apple devices. The IDE includes a code editor, a graphical user interface (GUI) builder, and various debugging tools. Xcode supports multiple programming languages, primarily Swift and Objective-C, and offers features like code completion and version control integration, streamlining the development process for both beginners and experienced developers.
