Creating different folder types in Xcode

In Xcode's **Project Navigator**, I see three types of container/folder icons:

So:


  • A yellow/golden folder (which I can create by right-clicking my project and going to New Group); and
  • A blue folder with squares inside of it; and
  • A blue folder with nothing inside of it


I'm wondering what these three "folder types" are, when to use them (and why) and how to create them.

Yellow is a virtual folder...simply a visual organizational convenience for the dev to help spot certain groups, collections, etc.


Blue is an actual folder you can also see in the Finder.
