Nah, C++ is mostly frowned upon inside Apple. The open source projects (clang and Darwin) contain most of the C++ in the OS. Objective-C is the ubiquitous implementation language in Apple's macOS/iOS/tvOS/watchOS userspace code. It will eventually be superseded by Swift as the Swift runtime improves. All userspace projects and some kernel projects are built in Xcode, and most developers internally use Xcode to edit the sources.
