Xcode "Add to Repository" Not Showing

If you have files to add to a SVN project but the Xcode's SCM->"Add to Repository" is not selectable, this tip may help you.  If the files to add are in a new folder you'll need to add the directory to the repository first.

1. From Xcode's menu go to SCM->Repository.
2. Navigate to the location where you want to create a directory and click on the "Create Directory" icon.
3. Update your local copy.  The new directory should appear in your local folders.
4. Copy your new files into the new folder.
5. Add and commit as normal.
