There are two types of any Xcode project structure organization:

• filesystem project structure (inspectable with Finder.app)
• IDE project structure (inspectable with Project Navigator in Xcode's navigator area.)

Xcode relies on filesystem organization by keeping a reference to a "physical" file or folder. That is why you may have all the classes, images, plists, and other parts of your projects stored in the same folder, while the references to these parts are being kept organized into respective groups within Xcode project.

When you create a group, it affects the organization of your project in Xcode. When you create a group with a reference folder, it creates both, a group in Xcode project and a folder in your filesystem.

However, since Xcode 9 it seems like, Apple enforces filesystem project structure to correspond to Xcode project structure. It means, that you explicitly has to choose "New Group without Folder"
