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 same issue and solved it by simply dragging the specified files from finder into the project navigator (ensuring that "copy files" is selected in the dialog) and committing the files.
