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

In my case, the file was missing from the source control.
To fix, I had to discard this file (be careful only discard the missing file not all your project):

1. Xcode->Source Control->commit
2. Right Click the missing file
3. Choose Discard Changes
