I tried the key bindings solution, but it I couldn't get it to work. However editing my XCode key bindings works like a charm. Here's how I made it.

This solution does not alter the contents of the Clipboard!

In the Edit User Scripts Dialog:

1. Duplicate the "Move Line Down" script and rename it
2. Duplicate the "Move Line Down.scpt" file, rename the script, select file via (double click) in Script Editor
3. Edit the script (Opens "AppleScript Editor") and remove the "delete (paragraphs startLine through endLine)" passage.
4. If you do not want to restart XCode, you seem to have to remove and re-add the script. Be sure that you have "Output" set to "Discard Output", otherwise you will have a "(null)" in your source file

Duplicate Line Up:

using terms from application "Xcode"
tell first text document
    set {startLine, endLine} to selected paragraph range

    if startLine > 1 then

        set theText to (theText as string)
        make new paragraph at beginning of paragraph (startLine) with data theText
        set selected paragraph range to {endLine + 1, endLine + endLine - startLine + 1}
    else
        beep 1
    end if
end tell
end using terms from

Duplicate Line Down:

using terms from application "Xcode"
tell first text document
    set {startLine, endLine} to selected paragraph range
    if endLine < (count paragraphs) then
        set theText to (paragraphs startLine through endLine)
        set theText to (theText as string)
        (* delete (paragraphs startLine through endLine) *)
        make new paragraph at beginning of paragraph (endLine + 1) with data theText
        set selected paragraph range to {startLine, endLine}
    else
        beep 1
    end if
end tell
end using terms from
