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.\"
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):
In my case it was a problem with git and a case-insensitive file system.
I had inadvertently submitted the same file twice, using file paths that differed only in case:
MyProject/Resources/foo.png
MyProject/resources/foo.png
Xcode was complaining about one of the missing files.
Fixed by deleting the offending files, and re-adding.
cd MyProject
mv Resources/foo.png /tmp
git rm Resources/foo.png
git rm resources/foo.png
git commit
mv /tmp/foo.png Resources
git add Resources/foo.png
git commit
I had to manually go into Terminal and remove the files with git rm ProjectPath\aaa\xxx.png
and then commit. After that everything worked fine.
I worked it out.
just open your third-party SVN tool, find the miss files, Revert; that's all.
To add onto Alexander Vasenin's answer...
First I Committed and Pushed my changes
Xcode Main Menu > Source Control > Commit
Then I Discarded All Changes to get rid of the errors
Xcode Main Menu > Source Control > Discard All Changes
After that, the errors stating "file xxx.png is missing from working copy" disappeared.
This is occurred when you delete file on Xcode, but didnt tell svn server about it.
Go to command line tool, and delete file directly.
svn delete missingFile.m
and commit it
svn commit -m "Deleting file"
note that if you delete .svn folder, the warning is disappear but you will lost communication with svn server.
