How do I get the current Date in short format in Swift

In the images below you can see the code I wrote and the values of all the variables:

class fun getCurrentShortDate() -> String {
    var todaysDate = NSDate()
    var dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "dd-MM-yyyy"
    var DateInFormat = dateFormatter.stringFromDate(todaysDate)

    return DateInFormat
}

Variable values

As you can see the current date is found no problem, but when I try to change the NSDate to a string, it just won't do it.

Late 2024 version.

A version of the above advice.

extension Date {

    /// Returns a pre-built data formatter used for localizing dates in the user's current Locale..
    /// Uses a .short dateStyle and .medium timeStyle.

    static var localizedDateFormatter: DateFormatter = {
        let formatter = DateFormatter()
        formatter.locale = Locale.current
        formatter.dateStyle = .short
        formatter.timeStyle = .medium
        return formatter
    }()
    
    /// Returns a string, describing self as a localized date in the user's current Locale.
    /// e.g. "9/10/2024, 14:31:03"
    
    var localizedDescription: String {
        return Date.localizedDateFormatter.string(from: self)
    }
}


print("Current date: \(Date.now.localizedDescription)"
// "Current date: 9/10/2024, 14:31:03"

Here is easiest way to change date format.

1. Create one swift class for Date extension.

extension Date {
    func today(format : String = "yyyy-MM-dd'T'HH:mm:ss.SSS") -> String {
        let formatter = DateFormatter()
        formatter.dateFormat = format
        return formatter.string(from: self)
    }
}

  1. How to use extension.

    let date = Date().today(format: "dd/MM/yy HH:mm:ss")

    print(date)

 let dateformatter1 = DateFormatter()
    dateformatter1.dateFormat = "ccc, d MMM yyy"

    let dateString1 = dateformatter1.string(from: datePicker.date)
    print("Date Selected \(dateString1)")
    labelDate.text = dateString1

    let dateformatter2 = DateFormatter()
    dateformatter2.dateFormat = "dd-MM-yyyy"
    let dateString2 = dateformatter2.string(from: datePicker.date)
    print("Date Selected \(dateString2)")


    let dateformatter3 = DateFormatter()
    dateformatter3.dateFormat = "dd/MM/yyyy"
    let dateString3 = dateformatter3.string(from: datePicker.date)
    print("Date Selected \(dateString3)")

    let dateformatter4 = DateFormatter()
    dateformatter4.dateFormat = "dd MMMM yyyy hh:mm a"
    let dateString4 = dateformatter4.string(from: datePicker.date)
    print("Date Selected \(dateString4)")

I referred this article on Codzify.com. Really helpful.

SWIFT 4 or 5

extension Date {

 static func getCurrentDate() -> String {

        let dateFormatter = DateFormatter()

        dateFormatter.dateFormat = "dd/MM/yyyy HH:mm:ss"

        return dateFormatter.string(from: Date())

    }
}

Using 

print(Date.getCurrentDate())

Here's the way Apple suggests

    let formatter = DateFormatter()
    formatter.locale = Locale.current
    formatter.dateStyle = .short
    let dateString = formatter.string(from: date)

or if the pre-defined format of .short, .medium, .long and .full are quite right create the template in a locale

    let formatter = DateFormatter()
    formatter.locale = Locale.current
    formatter.setLocalizedDateFormatFromTemplate("MM/dd/yyyy")
    let dateString = formatter.string(from: date)

Using the extension created by @doovers and some format strings from this website, you get the following:

extension Date {
    func string(format: String) -> String {
        let formatter = DateFormatter()
        formatter.dateFormat = format
        return formatter.string(from: self)
    }
}

Usage:

Date().string(format: "EEEE, MMM d, yyyy") // Saturday, Oct 21, 2017
Date().string(format: "MM/dd/yyyy")        // 10/21/2017
Date().string(format: "MM-dd-yyyy HH:mm")  // 10-21-2017 03:31

Date().string(format: "MMM d, h:mm a")     // Oct 21, 3:31 AM
Date().string(format: "MMMM yyyy")         // October 2017
Date().string(format: "MMM d, yyyy")       // Oct 21, 2017

Date().string(format: "E, d MMM yyyy HH:mm:ss Z") // Sat, 21 Oct 2017 03:31:40 +0000
Date().string(format: "yyyy-MM-dd'T'HH:mm:ssZ")   // 2017-10-21T03:31:40+0000
Date().string(format: "dd.MM.yy")                 // 21.10.17

You could also pass milliseconds to date object like this:

Date(1508577868947).string(format: "EEEE, MMM d, yyyy") // Saturday, Oct 21, 2017

Update for Swift 3.0: Create an extension for Date

extension Date {
    func string(format: String) -> String {
        let formatter = DateFormatter()
        formatter.dateFormat = format
        return formatter.string(from: self)
    }
}

Usage:

Date().string(format: "yyyy-MM-dd")

Swift 2.2: Create an extension for NSDate

extension NSDate {  
    func dateStringWithFormat(format: String) -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = format
        return dateFormatter.stringFromDate(self)
    }   
}

Usage:

NSDate().dateStringWithFormat("yyyy-MM-dd")

You can create a extension for easily transform a String into a NSDate.

extension NSDate {
    func dateFromString(date: String, format: String) -> NSDate {
        let formatter = NSDateFormatter()
        let locale = NSLocale(localeIdentifier: "en_US_POSIX")

        formatter.locale = locale
        formatter.dateFormat = format

        return formatter.dateFromString(date)!
    }
}

Than in your function you can NSDate().dateFromString("2015-02-04 23:29:28", format: "yyyy-MM-dd HH:mm:ss") and this should works. Input date don't need to be on the same format of output date.

func getCurrentShortDate() -> String {
    var todaysDate = NSDate().dateFromString("2015-02-04 23:29:28", format:  "yyyy-MM-dd HH:mm:ss")

    var dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "dd-MM-yyyy"
    var DateInFormat = dateFormatter.stringFromDate(todaysDate)

    return DateInFormat
}

println(getCurrentShortDate())

The output is 04-02-2015.
