Apple just released an update to OS X, and syncing Contacts and Calendars with iOS locally (i.e. over USB) is back in action. Like the good ole days, just open iTunes, highlight the connected device, and click the Info tab. After you update the operating system of course.
For those who might have followed the instructions for syncing with either the OwnCloud or OS X Server workarounds, those directions are now immediately obsolete. However, no matter the approach you used, remember to move Contacts and Calendar items back to On Your Mac or Main, respectively, before removing the WebDAV functionality those posts prescribed.
