Xcode Build System: Everything Everywhere All at Once
Curious about what really happens when you hit ‘Build’ in Xcode? This article breaks it down step by step in an easy-to-understand way. I explore each action Xcode takes behind the scenes, using simple explanations.

In addition to organizing all the files in each Xcode project, a workspace provides implicit and explicit relationships among the included projects and their targets. (c) Apple
It can contain many Xcode Projects.
