In this Ask A Dev, iOS Engineer Dan Murrell helps developers and advertisers prepare for next year's SXSW by explaining how to set up a geofence around downtown Austin, Texas.

He'll tell you what software and devices you need to familiarize yourself with before building your fence, as well as how to maximize your reach.
