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

It seems that this problem may have different causes, but it's often in relation with source control software.

In my case, I solved it by going to Git, and adding the files again. I mean running the following command:

git add .
