How can I convert string date to NSDate?

Question

I want to convert "2014-07-15 06:55:14.198000+00:00" this string date to NSDate in Swift.

Answer 1

For Swift 3

func stringToDate(_ str: String)->Date{
    let formatter = DateFormatter()
    formatter.dateFormat="yyyy-MM-dd hh:mm:ss Z"
    return formatter.date(from: str)!
}
func dateToString(_ str: Date)->String{
    var dateFormatter = DateFormatter()
    dateFormatter.timeStyle=DateFormatter.Style.short
    return dateFormatter.string(from: str)
}

Answer 2

FOR SWIFT 3.1

func convertDateStringToDate(longDate: String) -> String{

    /* INPUT: longDate = "2017-01-27T05:00:00.000Z"
     * OUTPUT: "1/26/17"
     * date_format_you_want_in_string from
     * http://userguide.icu-project.org/formatparse/datetime
     */

    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
    let date = dateFormatter.date(from: longDate)

    if date != nil {

        let formatter = DateFormatter()
        formatter.dateStyle = .short
        let dateShort = formatter.string(from: date!)

        return dateShort

    } else {

        return longDate

    }
}

NOTE: THIS WILL RETURN THE ORIGINAL STRING IF ERROR

Answer 3

Swift: iOS
if we have string, convert it to NSDate,

var dataString = profileValue["dob"] as String
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"

// convert string into date
let dateValue:NSDate? = dateFormatter.dateFromString(dataString)

if you have and date picker parse date like this

// to avoid any nil value
if let isDate = dateValue {
self.datePicker.date = isDate
}

If you're going to need to parse the string into a date often, you may want to move the functionality into an extension. I created a sharedCode.swift file and put my extensions there:

extension String
{   
    func toDateTime() -> NSDate
    {
        //Create Date Formatter
        let dateFormatter = NSDateFormatter()

        //Specify Format of String to Parse
        dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss.SSSSxxx"

        //Parse into NSDate
        let dateFromString : NSDate = dateFormatter.dateFromString(self)!

        //Return Parsed Date
        return dateFromString
    }
}

Then if you want to convert your string into a NSDate you can just write something like:

var myDate = myDateString.toDateTime()

Answer 5

Swift 3,4:

2 useful conversions:

string(from: Date) // to convert from Date to a String
date(from: String) // to convert from String to Date

Usage: 1.

let date = Date() //gives today's date
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd.MM.yyyy"
let todaysDateInUKFormat = dateFormatter.string(from: date)

2.

 let someDateInString = "23.06.2017"
 var getDateFromString = dateFormatter.date(from: someDateInString)

Answer 6

Swift 4

import Foundation

let dateString = "2014-07-15" // change to your date format

var dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

let date = dateFormatter.date(from: dateString)
println(date)

Swift 3

import Foundation

var dateString = "2014-07-15" // change to your date format

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

var date = dateFormatter.dateFromString(dateString)
println(date)

I can do it with this code.
