Missing file warnings showing up after upgrade to Xcode 4

Question

I recently upgraded to Xcode 4 (which is a great upgrade) but now I\'m getting some warnings that I did not get before. I have looked through forums and other SO posts but

Answer 1

The answer by Alex fixed my issue of missing files.

I had one other problem ( though it is not related to missing files, i feel this would be the better topic)

1. I needed to copy a set of images into my project.
2. I simply created a group (though i know that group doesnt map to the physical folder) and dragged the images into the group (selected "Copy to.." option).
3. SVN status showed all of them in "A".
4. Now when I went into actual file system, I found that all images where copied to the root folder of my project. As it didnt look well, I created a physical folder inside the images folder in my project and copied all the added images there.
5. SVN then showed all files in red.
6. I deleted the references of all the red files.
7. With the "Add File" option, I then added the images from the newly created folder.
8. Now SVN fails to show status of the files as "A", and no way I can check them in.
9. Tried out many steps like trashing them adding again from a different folder etc, but there wasnt any luck.

I fixed this by going directly into the repository, create a new directory under images so that the physical folder is now in the SVN server

I then took an update of the source, and got the newly created directory inside my working copy (though it is not added to the project).

I then copied the images to that directory and added them to the project using "Add File" option, which brought me back the "A" status and I was able to check in the files.

Just wanted to share this.....because it took a lot of time from me.
