Xenoblade Chronicles doesn't swing the Wiimote or the Nunchuk. I can't find any mention of it in the manual or online: http://strategywiki.org/wiki/Xenoblade_Chronicles/Controls
The swing controls for Xenoblade Chronicles aren't responding because they aren't used. Have you tried another game that requires you to swing the nunchuk, like Super Mario Galaxy?
