Xcode: issue “file xxx.png is missing from working copy” at project building

Question

After deleting/adding some png files to project, i have got messages when building project.

\"file ProjectPath\\aaa\\xxx.png is missing from working copy.\"

Answer 1

I had the warnings, and also could not commit changes under XCode (using svn). All I had to do was restart XCode and the problem went away.
