I am getting a date in response from the server which i want to display in the label but when i am displaying it, nil is returned plz help.
my code:
let pulledDate = "2018-04-27T02:05:00+00:00"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZ"
let date = dateFormatter.date(from: pulledDate!) // nil
You can use like this:
You were passing the Wrong Format I guess
Way One
let pulledDate = "2018-04-27T02:05:00+00:00"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZZZZZ"
let date = dateFormatter.date(from: pulledDate)
print(date!)
The Output
Way Two
let pulledDate = "2018-04-27T02:05:00+00:00"
let dateFormatter = ISO8601DateFormatter()
let date = dateFormatter.date(from: pulledDate)
print(date!)
The Output:
Use it the Way you Want.
Hope this help.

All,
I am trying to convert UTC date to local date . Below is my code. But, even after converting I get both dates in UTC only.
static func getTodayDateInLocalTimeZone() -> Date{
let todaydateInUTC = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
dateFormatter.timeZone = TimeZone(identifier: "UTC")
let utcDateString = dateFormatter.string(from: todaydateInUTC)
print("Date::: utcDateString: \(utcDateString)")
// Changing to Current timezone
let timzoneIdentiier = TimeZone.current.identifier
let timezone = TimeZone(identifier: timzoneIdentiier)
let abbrv = timezone?.abbreviation()
let dateFormatter1 = DateFormatter()
dateFormatter1.timeZone = TimeZone(identifier: abbrv!)
dateFormatter1.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
print("Date:::timeZone: \(timzoneIdentiier) == \(String(describing: abbrv))")
let formattedDate1 = dateFormatter1.date(from: utcDateString)
print("Date:::: \(formattedDate1)")
return formattedDate1!
}
Here is what I get when I print
Date::: utcDateString: 2021-01-20T17:39:15+0000
Date:::timeZone: America/New_York == Optional("EST")
Date:::: Optional(2021-01-20 17:39:15 +0000)
Please let me know why is it now changing to the local timezone.
Thanks
First of all, a date does not have a time zone.
So let todaydateInUTC = Date() actually means let todaydate = Date().
The time zone becomes relevant, when you want to present a date to the user.
So instead of creating a new date from a the utcDateString, you just need to create another date string from the same date variable.
let formattedDate1 = dateFormatter1.date(from: utcDateString) becomes let tzDateString = dateFormatter1.string(from: todaydate).
This also means your function should return a string instead of a date.
For example:
func getTodayDateInLocalTimeZone() -> String
{
let now = Date()
// Just for debugging. Not for the result.
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
dateFormatter.timeZone = TimeZone(identifier: "UTC")
let utcDateString = dateFormatter.string(from: now)
print("Date::: utcDateString: \(utcDateString)")
let tz = TimeZone.current
let dateFormatter1 = DateFormatter()
dateFormatter1.timeZone = tz
dateFormatter1.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ"
print("Date:::timeZone: \(tz) == \(String(describing: tz.abbreviation()))")
let tzDateString = dateFormatter1.string(from: now)
print("Date:::: \(tzDateString)")
return tzDateString
}
For me it results in:
Date::: utcDateString: 2021-01-20T18:19:44+0000
Date:::timeZone: Europe/Berlin (current) == Optional("CET")
Date:::: 2021-01-20T19:19:44+0100
I am getting date string from server like that "2017-08-05T00:30:00.000+02:00". Below is my code for date formatter.
let dateFormatter: DateFormatter = DateFormatter()
let serverDateString = "2017-08-05T00:30:00.000+02:00"
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZZ"
dateFormatter.locale = Foundation.Locale(identifier: "en_US_POSIX")
let currentDate: Date = dateFormatter.date(from: serverDateString)!
But it returns 2017-08-04 22:30:00 +0000. Which is wrong. Any suggestions?
In Swift 3
You can change your server time string to UTC time Date as:
let dateFormatter: DateFormatter = DateFormatter()
var serverDateString = "2017-08-05T00:30:00.000+02:00"
let index = serverDateString.index(serverDateString.startIndex, offsetBy: 19)
serverDateString = serverDateString.substring(to: index)
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
dateFormatter.timeZone = TimeZone.init(identifier: "UTC")
let currentDate: Date = dateFormatter.date(from: serverDateString)!
Your Code for parsing date is correct: 2017-08-05T00:30:00.000+02:00 and 2017-08-04 22:30:00 +0000 represent the same time, just in different time zones. Your only problem is that Date doesn't actually store the time zone
yyyy-MM-dd'T'hh:mm:ss.SSSZZZZZZ
This is correct date formate for your input string. Here is the Apple Document for more description.
Here is my code:
var strInputDateString: String = "2017-08-05T00:30:00.000+02:00"
var dateFormat = DateFormatter()
dateFormat.dateFormat = "yyyy-MM-dd'T'hh:mm:ss.SSSZZZZZZ"
//Set new dateFormate
var date1: Date? = dateFormat.date(from: strInputDateString)
dateFormat.dateFormat = "dd-MM-YYYY hh:mm:ss"
// Your Desire
var strOutputDateString: String = dateFormat.string(from: date1!)
print("\(strInputDateString)")
print("\(strOutputDateString)")
output:
Main input String:2017-08-05T00:30:00.000+02:00
Converted String: 05-08-2017 04:00:00
For now, I tried to convert your date format with my custom. It's give me the perfect output.
Actually, your code is good.
I copied your data and ran it in playground.
What kind of format you want it be?
Try this
let dateFormatter: DateFormatter = DateFormatter()
let serverDateString = "2017-08-05T00:30:00.000+02:00"
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssXXX"
dateFormatter.locale = Foundation.Locale(identifier: "en_US_POSIX")
let currentDate: Date = dateFormatter.date(from: serverDateString)!
Hope this helps
The step you are missing is to again use your DateFormatter to format the date into a string. When you use print on the date, it will always show GMT. For illustration purposes, I've set the TimeZone to Berlin to match the original offset of +2:00.
let dateFormatter: DateFormatter = DateFormatter()
let serverDateString = "2017-08-05T00:30:00.000+02:00"
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZZZZZZ"
// Hard set to Berlin
dateFormatter.timeZone = TimeZone(identifier: "Europe/Berlin")
let currentDate: Date = dateFormatter.date(from: serverDateString)!
// Your missing step
dateFormatter.string(from: currentDate)
Remember that DateFormatters are about:
Parsing from a String - df.date(from: String)
Formatting from a Date - df.string(from: Date)
I want this date "2016-10-18 22:06:20 +0000" to "18-10-2016", is this possible? I managed to get the date as follows:
var formatter = DateFormatter()
formatter.dateFormat = "yyy-MM-dd'HH:mm:ss.SSSZ"
let stringDate = formatter.string(from: currentDate)
The above gives me "10/18/16", but how can I get "18-10-2016"?
Solution in Swift 3
extension Foundation.Date {
func dashedStringFromDate() -> String {
let dateFormatter = DateFormatter()
let date = self
dateFormatter.dateFormat = "dd-MM-yyyy"
return dateFormatter.string(from: date)
}
}
Example
let date = Foundation.Date()
let formatedDate = date.dashedStringFromDate()
Little about what you put in your question makes a lot of sense. You don't have a date as 2016-10-18 22:06:20 +0000. The code you posted converts a current Date into a string. But you claim you want that string to be in the format 18-10-2016 but your code uses a completely different format.
Why not just do:
var formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy"
let stringDate = formatter.string(from: currentDate)
This will convert the currentDate to a string in the format you mention in your question.
If you really have a string in the format of 2016-10-18 22:06:20 +0000 and you want to convert it to 18-10-2016, then you want two date formatters.
The first convert that original string to a date:
let string = "2016-10-18 22:06:20 +0000"
let formatter1 = DateFormatter()
formatter1.locale = Locale(identifier: "en_US_POSIX") // if this string was from web service or a database, you should set the locale
formatter1.dateFormat = "yyyy-MM-dd HH:mm:ss Z"
guard let date = formatter1.date(from: string) else {
fatalError("Couldn't parse original date string")
}
If you then want to build a new string in the format of 18-10-2016, then you'd use a second formatter:
let formatter2 = DateFormatter()
formatter2.dateFormat = "dd-MM-yyyy"
let result = formatter2.string(from: date)
I have a date string in this format:
2016-06-20T13:01:46.457+02:00
and I need to change it to something like this:
20/06/2016
Previously I have always used this library -> SwiftDate to manipulate the dates, but it doesn't work now.
I tried also something like:
let myDate = self.dateNoteDict[indexPath.row]!
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss.SSSSxxx"
let date = dateFormatter.dateFromString(myDate)
print("date -> \(date)")
but it doesn't work. How can I do?
Thanks in advance.
The standard ISO8601 date format with fractional seconds and time zone is
yyyy-MM-dd'T'HH:mm:ss.SSSZ
let myDate = "2016-06-20T13:01:46.457+02:00"
let dateFormatter = NSDateFormatter()
dateFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX") // edited
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = dateFormatter.dateFromString(myDate)!
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.stringFromDate(date)
Swift 3:
let myDate = "2016-06-20T13:01:46.457+02:00"
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX") // edited
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = dateFormatter.date(from:myDate)!
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.string(from:date)
In macOS 10.13+, iOS 11+ ISO8601DateFormatter is an alternative as input formatter
let myDate = "2016-06-20T13:01:46.457+02:00"
let inputFormatter = ISO8601DateFormatter()
inputFormatter.formatOptions = [.withFullDate, .withFullTime, .withFractionalSeconds]
let date = dateFormatter.date(from:myDate)!
let outputFormatter = DateFormatter()
outputFormatter.locale = Locale(identifier: "en_US_POSIX")
outputFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.string(from:date)
I always use this code while converting String to Date .
(Swift 3)
extension String
{
func toDate( dateFormat format : String) -> Date
{
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = format
if let date = dateFormatter.date(from: self)
{
return date
}
print("Invalid arguments ! Returning Current Date . ")
return Date()
}
}
and just call like . .
print ( "2016-06-20T13:01:46.457+02:00".toDate(dateFormat: "yyyy-MM-dd'T'HH:mm:ss.SSSZ") )
//Capital HH for 24-Hour Time
I always use this code while converting String to Date. (Swift 4.2)
let myDate = datePicker.date
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = myDate
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.string(from:date)
print(dateString)
You can try manually also:
let myDate = "2019-02-22T08:21:11+0000"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = myDate
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateString = dateFormatter.string(from:date)
print(dateString)
hello I have a date like this
2016-02-10 00:00:00
I want to get only date from it in this style
14.05.2016 or 14-05-2016
This is what I have tried
let dateFormatter = NSDateFormatter()
let date = "2016-02-10 00:00:00"
dateFormatter.dateFormat = "dd-MM-yyyy"
let newdate = dateFormatter.dateFromString(date)
print(newdate) //nil is coming
A better way than proposed versions is not to convert from date using a string formatter, but instead using calendar:
public func removeTimeStamp(fromDate: Date) -> Date {
guard let date = Calendar.current.date(from: Calendar.current.dateComponents([.year, .month, .day], from: fromDate)) else {
fatalError("Failed to strip time from Date object")
}
return date
}
Using an extension on the Date:
extension Date {
public var removeTimeStamp : Date? {
guard let date = Calendar.current.date(from: Calendar.current.dateComponents([.year, .month, .day], from: self)) else {
return nil
}
return date
}
}
Usage:
let now = Date()
let nowWithouTime = now.removeTimeStamp
okay I solved this myself
let date = "2016-02-10 00:00:00"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
let dateFromString : NSDate = dateFormatter.dateFromString(date)!
dateFormatter.dateFormat = "dd-MM-yyyy"
let datenew= dateFormatter.stringFromDate(dateFromString)
print(datenew)
Your code is not correct.
If you have NSDate instance that you want to convert to String using NSDateFormatter
You use this code:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dateString = dateFormatter.stringFromDate(date)
The problem in your code is that you have a date string with value 2016-02-10 00:00:00 but you parse it using date format `dd-MM-yyyy' this is why you get a nil Date.
Instead you need to parse it first using dateFormatter.dateFormat = "yyy-MM-dd hh:mm:ss"
Swift 5.5+
Use formatted(_:)
let now = Date.now
let date = now.formatted(.iso8601.year().month().day().dateSeparator(.dash))
Or formatted(date:time:)
let now = Date.now
let date = now.formatted(date: .abbreviated, time: .omitted)
Instead of .abbreviated, you may use a DateStyle such as .long, or .numeric.

If you have an input date string (or rather, date-and-time string) in one format and you want to output in a different format then you need 2 date formatters: An input formatter that takes the source string format and converts it to an NSDate (using dateFromString) and then an output formatter that takes the NSDate and converts it to your output date string (using stringFromDate).
Your code is wrong because you are creating a date formatter configured for your output date string format and trying to use it to convert your input date string to an NSDate.
I am not an expert on NSDateFormatter date strings. Any time I need to work with them I have to dig out the docs and figure out the solution to the specific problem I'm trying to solve. Thus I'm going to leave that part of the problem to you. Suffice it to say that you'll need an input date formatter that uses a format string that exactly matches the format of your input date string. This can be tricky because if it isn't exactly correct it simply fails and returns a nil NSDate.
The output date formatter is easier because if it isn't quite right, your output date will not look the way you want it to look but that will be obvious.
Recommend you to use library SwiftDate with dozen of handy options.
For your case use date truncating e.g.:
let date = "2017-07-22 15:03:50".toDate("yyyy-MM-dd HH:mm:ss", region: rome)
let truncatedTime = date.dateTruncated(from: .hour) // 2017-07-22T00:00:00+02:00
For Swift 4 and above, You can go with the following code
let date = "2016-02-10 00:00:00"
let dateFormatter = DateFormatter()
let date = modelDeals.dealItemInDetail?.validTo ?? ""
dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
let dateFromString : NSDate = dateFormatter.date(from: date)! as NSDate
dateFormatter.dateFormat = "dd-MM-yyyy"
let datenew = dateFormatter.string(from: dateFromString as Date)
For swift : (Swift 3) applications,
if you are using Date() objects make sure you set timeStyle
of DateFormatter() to none
Example:
let today = Date()
let dateFormatter = DateFormatter()
//dateFormatter.dateFormat = "yyyy-MM-dd", upto you
dateFormatter.dateFormat = "dd-MM-yyyy"
//This is Important!
dateFormatter.timeStyle = DateTimeFormatter.Style.none
let dateString = dateFormatter.string(from: today)
Swift 3 Version:
let date = "2016-02-10"
let dateformater = DateFormatter()
dateformater.dateFormat = "YYYY-MM-dd"
let dateString = dateformater.date(from: date)
//print date
print(dateString)
