I am trying to delete a working copy of my project, I came across this answer
Xcode Source Control showing multiple Working Copies
But seems that in Xcode 7.3.1 ( I don't know which version they change it) there is no file "xcshareddata" mentioned in the answer
So I don't know how to achieve it in my Xcode
First please select shared in manage scheme: set the active scheme (next to stop button) -> manage schemes -> click the scheme -> edit -> select shared in the bottom of the window
Then open the xcode project folder -> projectname.xcodeproj -> show Package Conents -> xcshareddata -> schemes -> edit and save file
