Darwin is the open-source operating system developed by Apple Inc. It forms the core (or foundation) of macOS, iOS, watchOS, and tvOS. Darwin incorporates elements from various sources, including a Unix-based foundation, and employs components from the XNU kernel, which combines components from both the Mach microkernel and components from BSD (Berkeley Software Distribution).
