I just tried to make a copy of an X-code project (perhaps ironically, for back up purposes) by alt+dragging to another folder.
Instead I accidentally just dragged it and X-code complained about this (I know, I should’ve closed X-Code before attempting to copy the folder) so I moved it back immediately.
X-code insisted it either re-save or close, so I opted for close.
When I reopened it, my MainStoryboard was gone (red typeface in the explorer).
Anyone know if it’s possible to retrieve it?
Not much help to anyone but switching the Mac on and off again restored the file, which was a nice surprise.
