How do you see files that you add externally?
Files cannot be added externally. Dumping a source file into the project directory does not add it to the project. To add a file you must add it to the project from within Xcode.
If you have a bunch of files that you need to add then in the Add File dialog you can just select all the files you want at once and add them, without having to repeatedly open the Add File dialog. Just use control clicking to select multiple files.
