What is an XCWORKSPACE file?
File created by Xcode, a development application for creating iOS and Mac OS X (Cocoa) applications; saves workspace settings including and the View (Navigator, Debug, and Utilities panes) and Editor states; created by selecting File → Save As Workspace... with an open project.
When you open an XCWORKSPACE file, it opens the associated project and restores the perspective. Therefore, Xcode workspace files can be used as a wrapper or container for an Xcode .XCODEPROJ project.
