I am using Xcode 4.3.2 and I am trying to add some SDK references to my project. I can SEE the files using Finder, as I used the terminal script to view hidden files. Yet, when I go to my user home directory in Xcode finder, it does not show the "hidden" 'Library' folder under my user profile that stores my SDK files.
Scratching head
Press and hold the ⌘ + shift and . keys at the same time.
Then you can switch to view hidden/non-hidden files.
Answering you 9 months later from OS X 10.8 Mountain Lion...
Press ⌘ShiftG from within Xcode's Open dialog -- this is the Go To Folder command from Finder. This works in XCode's Open dialog as well. You could go to 'Library' or, as I did below, go to the otherwise hidden .config directory by typing '.config'
This screenshot shows both the process & the result of opening the .config folder. Note that I've already 'gone' to the .config folder once, which is why it's displayed on the left, above Applications.
Which command are you Using ? Use Bellow Command it worked for me.
If the Library folder is not visible in your folder, enter the command "chflags nohidden ~/Library/ " on Terminal(Applications->Utilities->Terminal) application
Had a similar problem (but arrived on this page looking for answers).
I removed a reference to a file in XCode which I actually wanted to keep but the file still existed in finder.
Even though the file is in the correct folder, Xcode won't acknowledge it until you re-add it via File > Add Files To "YourProject"
The point I'm making is that the files in your code project folders vs. those actually included in the XCode project are two different things
