Some little Swift helper functions for dealing with dates.

Helpers.swift

//Use as follows
//let dateHelper = Helpers()
//let dateString: String = row["dateString"] as! String
//label.text = dateHelper.getFormattedDate(dateString)

import Foundation

        formatter.locale = NSLocale.currentLocale()
        let date = formatter.dateFromString(date)
        
        formatter.locale = NSLocale.currentLocale()
        formatter.dateStyle = .ShortStyle
        formatter.timeStyle = .NoStyle
        let formattedDate = formatter.stringFromDate(date!)
        
        return formattedDate
