On my MacBookPro, using the Finder, when I right click on MyApp.xcodeproj and select display content of package only one file and two folders are displayed :

project.xcworkspace
xcshareddata
xcuserdata 

But if I use Terminal to navigate to MyApp.xcodeproj and list the content I can see

project.pbxproj
project.xcworkspace
xcshareddata
xcuserdata

How come project.pbxproj does not show up in Finder ?
