The following will display the coordinated universal time and the local system date and time using Swift.

The code

//
//  main.swift
//  ConsoleApp1


import Foundation

let date = NSDate();
let dateFormatter = NSDateFormatter()
//To prevent displaying either date or time, set the desired style to NoStyle.
dateFormatter.timeStyle = NSDateFormatterStyle.MediumStyle //Set time style
dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle //Set date style
dateFormatter.timeZone = NSTimeZone()
let localDate = dateFormatter.stringFromDate(date)

println("UTC Time")
println(date)
println("Local Time")
println(localDate)

The output:

UTC Time
