The class NSDateFormatter is an easy-to-use tool. Just like SimpleDateFormat in Java.

Convert String to NSDate

let str = "2016-06-01T00:00:00Z"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
let date = dateFormatter.dateFromString(str)

Convert NSDate to String

let description = "Time is \(dateFormatter.stringFromDate(date))"
