Swift 3 Changing Date Format

Swift 3 changing date format

Your code is completely wrong. Just do the following:

@IBAction func datePickerChanged(_ sender: UIDatePicker) {
    let formatter = DateFormatter()
    formatter.dateFormat = "dd.MM.yyyy HH:mm"

    dateLabel.text = formatter.string(from: sender.date)
}

This will convert the date picker's chosen date to a string in the format dd.MM.yyyy HH:mm in local time.

Never use the description method to convert any object to a user presented value.

Date Format in Swift

You have to declare 2 different NSDateFormatters, the first to convert the string to a NSDate and the second to print the date in your format.

Try this code:

let dateFormatterGet = NSDateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"

let dateFormatterPrint = NSDateFormatter()
dateFormatterPrint.dateFormat = "MMM dd,yyyy"

let date: NSDate? = dateFormatterGet.dateFromString("2016-02-29 12:24:26")
print(dateFormatterPrint.stringFromDate(date!))

Swift 3 and higher:

From Swift 3 NSDate class has been changed to Date and NSDateFormatter to DateFormatter.

let dateFormatterGet = DateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"

let dateFormatterPrint = DateFormatter()
dateFormatterPrint.dateFormat = "MMM dd,yyyy"

if let date = dateFormatterGet.date(from: "2016-02-29 12:24:26") {
    print(dateFormatterPrint.string(from: date))
} else {
   print("There was an error decoding the string")
}

How to change the time format in calendar swift 3

Set the FSCalendar deleget and try this code:

func calendar(_ calendar: FSCalendar, shouldSelect date: Date, at monthPosition: FSCalendarMonthPosition) -> Bool {
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "dd-MM-yyyy"
    let dateString = dateFormatter.string(from: date as Date)
    print("Selected Date: \(dateString)")
    return true
}

Unable to change format of date in swift

You are doing it wrong. If you need to show the date, you use a formatted String and not the Date object.

func getDate() -> String {
    let formatter = DateFormatter()
    // Set the appropriate time zone or locale
    formatter.dateFormat = "dd/MM/yyyy HH:mm"
    return formatter.string(from: self)
}

How to convert date format from dd/MM/YYYY to YYYY-MM-dd in swift

First changes your year formatter with yyyy and instead of using two NSDateFormatter use just one like this

let inputFormatter = NSDateFormatter()
inputFormatter.dateFormat = "MM/dd/yyyy"
let showDate = inputFormatter.dateFromString("07/21/2016")
inputFormatter.dateFormat = "yyyy-MM-dd"
let resultString = inputFormatter.stringFromDate(showDate!)
print(resultString)

For Swift3 and later

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM/dd/yyyy"
let date = dateFormatter.date(from: date)
dateFormatter.dateFormat = "yyyy-MM-dd"
let resultString = dateFormatter.string(from: date!)
print(resultString)

How to convert date string into date in swift 3

Use this string class extension

   extension String {
    func date(format: String) -> Date? {
            let dateFormatter = DateFormatter()
            dateFormatter.dateFormat = format
            dateFormatter.timeZone =TimeZone.current
            let date = dateFormatter.date(from: self)
            return date
        }
    }

use above function like this

let date = "07/06/2017 11:23 AM".date(format:"MM/dd/yyyy HH:mm a")

Date formatting not working in Swift 3

Date().toString() // convert date to string with userdefined format.

extension Date {
        func toString() -> String {
            let dateFormatter = DateFormatter()
            dateFormatter.dateFormat = "MMMM dd yyyy"
            return dateFormatter.string(from: self)
        }
    }
