I actually think Visual Studio does refactoring pretty well. It is not a new innovation from Apple. Xcode, in this case, is just catching up with a much needed feature and I still think it's not quite there.

It looks the implementation was a significant investment. They built a language-agnostic refactoring engine into Clang and open-sourced it http://lists.llvm.org/pipermail/cfe-dev/2017-June/054286.htm...
