let dateShow = formatter.dateFromString(v["feedDate"].description) I would first check if v["feedDate"] isn't an optional, because in this case the v["feedDate"].description would probably contain string like Optional("2015-05-10T18:39:55+02:00") as opposed to 2015-05-10T18:39:55+02:00, which obviously won't get converted to NSDate...
