Problems with NSDateFormatter

Hi,

I'm getting a "Bummer Message" on a coding exercise. It says I should use the short style. Would someone please tell wj=hat I'm doing wrong? Thanks.

date_formatter.swift
import Foundation
let secondsSinceBirth = NSTimeInterval(1200000000)
var dateOfBirth = NSDate(timeIntervalSince1970: secondsSinceBirth)
let dateFormatter = NSDateFormatter()
dateFormatter.dateStyle = .ShortStyle
var stringDate = dateFormatter.stringFromDate(dateOfBirth)

Take a look at this code:

import Foundation
let secondsSinceBirth = NSTimeInterval(1200000000)
var dateOfBirth = NSDate(timeIntervalSince1970: secondsSinceBirth)

let dateFormatter = NSDateFormatter()
dateFormatter.timeStyle = .ShortStyle
dateFormatter.dateStyle = .MediumStyle

var stringDate = dateFormatter.stringFromDate(dateOfBirth)

I should add that this same snippet works well in xCode.

Thank you, Caleb. That worked. I still don't understand why those styles were required in the challenge. The way I read the instructions, I should have left the time format style alone, and set the date format style to short.
