I have been working on a Cocoa app, and found two files to be missing, a matching *h/*m pair that is the crux of my application. The files are marked in red in XCode, and and non-existent in my source directory. Instead, I've found skeleton files for these under ImageView-1.moved-aside/ ImageView is the name of the application. Does anybody know what could have caused this? Both for the deletion of files and the creation of skeleton files in moved-aside? Most strangely, I backed up all files on December 24th, and last compiled the application on December 29th, yet the files are missing both from my backup (a tar file) and the original source.
