At a loss currently with this piece of code. Would be great if anyone could help!

Not quite sure what I have done wrongly.

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

let dateFormatter = NSDateFormatter()
dateFormatter.timeStyle = .ShortStyle
dateFormatter.dateStyle: NSDateFormatterMediumStyle
return dateFormatter.stringFromDate(dateOfBirth)

var stringDate = "Jan 2, 2015"

Hi Jamal,

The code you need looks like:

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

dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle
dateFormatter.timeStyle = .ShortStyle
let stringDate = dateFormatter.stringFromDate(dateOfBirth)

So, first we create an instance of the NSDateFormatter, as you have done.

Next, we access the dateStyle and timeStyle and set the appropriate style, as required. Lastly, we use the stringFromDate method and pass it the string that was provided.

I hope that all makes sense!

Steve.
