Question

In Xcode how do I create a new workspace and add 1 project to it so that I can see the project and its files?

If I just drag in the project, all I can see is the project

Just FYI, 2020, Apple recently added a thing,

1. make your workspace, exit it and

2. make your new project. in fact when you enter the name to save the project,

they added this option:

just select the workspace you wish to add it to.
