Answer 1

You can use DateFormatter as follow:

extension Formatter {
    static let monthMedium: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "LLL"
        return formatter
    }()
    static let hour12: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "h"
        return formatter
    }()
    static let minute0x: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "mm"
        return formatter
    }()
    static let amPM: DateFormatter = {
        let formatter = DateFormatter()
        formatter.dateFormat = "a"
        return formatter
    }()
}
extension Date {
    var monthMedium: String  { return Formatter.monthMedium.string(from: self) }
    var hour12:  String      { return Formatter.hour12.string(from: self) }
    var minute0x: String     { return Formatter.minute0x.string(from: self) }
    var amPM: String         { return Formatter.amPM.string(from: self) }
}

---

let date = Date()

let dateMonth  = date.monthMedium  // "May"
let dateHour   = date.hour12       // "1"
let dateMinute = date.minute0x     // "18"
let dateAmPm = date.amPM           // "PM"

Answer 2

I am adding three types. Have a look.

        //Todays Date
        let todayDate = NSDate()
        let calendar = NSCalendar(identifier: NSCalendarIdentifierGregorian)!
        let components = calendar.components(.CalendarUnitYear | .CalendarUnitMonth | .CalendarUnitDay, fromDate: todayDate)
        var (year, month, date) = (components.year, components.month, components.day)
        println("YEAR: \(year)  MONTH: \(month) DATE: \(date)")

        //Making a X mas Yr
        let morningOfChristmasComponents = NSDateComponents()
        morningOfChristmasComponents.year = 2014
        morningOfChristmasComponents.month = 12
        morningOfChristmasComponents.day = 25
        morningOfChristmasComponents.hour = 7
        morningOfChristmasComponents.minute = 0
        morningOfChristmasComponents.second = 0

        let morningOfChristmas = NSCalendar.currentCalendar().dateFromComponents(morningOfChristmasComponents)!
        let formatter = NSDateFormatter()
        formatter.dateStyle = NSDateFormatterStyle.LongStyle
        formatter.timeStyle = .MediumStyle
        let dateString = formatter.stringFromDate(morningOfChristmas)
        print("dateString : \(dateString)")


        //Current month - complete name
        let dateFormatter: NSDateFormatter = NSDateFormatter()
        let months = dateFormatter.monthSymbols
        let monthSymbol = months[month-1] as! String
        println("monthSymbol  : \(monthSymbol)")


Print Results:

YEAR: 2015  MONTH: 10 DATE: 9
dateString : December 25, 2014 at 7:00:00 AM
monthSymbol  : October

Answer 3

NSDateFormatter has monthSymbols, shortMonthSymbols and veryShortSymbols properties.

So try this:

let dateFormatter: NSDateFormatter = NSDateFormatter()

let months = dateFormatter.shortMonthSymbols
let monthSymbol = months[month-1] as! String // month - from your date components

println(monthSymbol)

Update Swift 5.x Solution:

Today is Monday, 20 April, 2020

    let date = Date() // get a current date instance
    let dateFormatter = DateFormatter() // get a date formatter instance
    let calendar = dateFormatter.calendar // get a calendar instance

Now you can get every index value of year, month, week, day everything what you want as follows:

    let year = calendar?.component(.year, from: date) // Result: 2020
    let month = calendar?.component(.month, from: date) // Result: 4
    let week = calendar?.component(.weekOfMonth, from: date) // Result: 4
    let day = calendar?.component(.day, from: date) // Result: 20
    let weekday = calendar?.component(.weekday, from: date) // Result: 2
    let weekdayOrdinal = calendar?.component(.weekdayOrdinal, from: date) // Result: 3
    let weekOfYear = calendar?.component(.weekOfYear, from: date) // Result: 17

You can get an array of all month names like:

    let monthsWithFullName = dateFormatter.monthSymbols // Result: ["January”, "February”, "March”, "April”, "May”, "June”, "July”, "August”, "September”, "October”, "November”, "December”]
    let monthsWithShortName = dateFormatter.shortMonthSymbols // Result: ["Jan”, "Feb”, "Mar”, "Apr”, "May”, "Jun”, "Jul”, "Aug”, "Sep”, "Oct”, "Nov”, "Dec”]

You can format current date as you wish like:

    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
    let todayWithTime = dateFormatter.string(from: date) // Result: "2020-04-20 06:17:29"
    dateFormatter.dateFormat = "yyyy-MM-dd"
    let onlyTodayDate = dateFormatter.string(from: date) // Result: "2020-04-20"

I think this is the most simpler and updated answer.

Swift 4.x Solution:
