My computers hard drive is full, and while I edited a .h file in xcode it said it can't be autosaved (obviously), but then the file name in the navigation area turned red and I wasn't able to get into the file. This happened to two files, and one of them went available again after deleting some files but one isn't even though I have cleared space. I can't seem to find it in the project directory neither. What has happened, is my file deleted?
If in the Xcode the filename turns red, that means that Xcode is missing reference to the file, which can mean that the file is either deleted or renamed.
