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

I solved it the following way:

1. Check the path to the missing file.
2. Create missing files at appropriate locations within your project directory
3. Add them to your project using "Add Files to "project"" and create references only (do not copy the files)
4. The warnings should disappear at this point.
5. From within Xcode delete the files making sure you click "Delete" instead of the default "Delete Reference Only"
6. You're done.
