I have a playground ~/Rope.playground/ and associates sources under
~/Rope.playground/Sources/. Xcode frequently creates new folders,
~/Rope.playground/ and ~/Rope.playground/Sources/, copies my .swift
files there, and then deletes the originals. This plays havoc with my
editing the source files with
Any ideas why Xcode does this and how/whether I can stop it?
I have only noticed this happening in a playground. Xcode otherwise
seems to cooperate pretty well with an external editor.
