macOS Xcode: "Unknown Error. Failed to Save."

I'm continually getting this error whenever I open up a project in Xcode or when I close a project. Anybody had any similar problems? I've tried a fresh install from the Mac App Store and only using a freshly made project file.

I also sometimes get "The file 'main.cpp' is locked and cannot be saved", even though the file isn't locked.

Do you have the write privilege for the directory of the project?

Click to expand...

Read & Write has been set for everything and all enclosing folders for everything even remotely close to where it's being saved (My Home Folder > Documents)

Is the folder locked? Locked takes precedence over having write permission.

Try this command in Terminal.app (copy and paste it):

Code:

ls -lOR ~/Documents | grep chg

Post any output.

Didn't get any output, and still getting the same error.
