HI I am trying to formate date from string (08-05-1988) I want to convert to date as given below, output also given below,
let dateString = "08-05-1988"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dateFromString = dateFormatter.date(from: dateString)
let stringValue = String(describing: dateFromString)
out put : Optional(1988-05-07 18:30:00 +0000)
Then, I want to format the out put date from (1988-05-07 18:30:00 +0000) to other format as given below. But, when format the string to Date is nil
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-mm-dd hh:mm:ss Z"
let date = dateFormatter.date(from: dateString)
let formatter = DateFormatter()
formatter.dateFormat = "dd-MMM-yyyy"
let formatedDate:String = formatter.string(from: date!)
Expected Output : 08-May-1988
The output Optional(1988-05-07 18:30:00 +0000) is the result of the description of a Date object. It's not related to any given string format.
To convert 08-05-1988 to 08-May-1988 you can simply use
let dateString = "08-05-1988"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dateFromString = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "dd-MMM-yyyy"
let formatedDate = dateFormatter.string(from: dateFromString!)
let date = Date()
let format = DateFormatter()
format.dateFormat = "dd-MM-yyyy"
let formatDate = format.string(from: date)
You're calling dateFormatter.date on dateString instead of dateFromString. Since "08-05-1988" doesn't match the specified format of "yyyy-mm-dd hh:mm:ss Z", dateFormatter.date returns nil.

I am getting date in string format from server. So I am trying to formatting to particular format.
But it is getting nil.
"07September16 4:09 am", This I want to format like Sep 07 2016
I am doing it with following code
dateLabel.text = model().formatStringToDate(dateString: date)
func formatStringToDate(dateString: String) -> String {
let dateStr = dateString
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MMM d yyyy"
let formattedDate = dateFormatter.date(from: dateStr)
print("formattedDate \(formattedDate)")
//I have to return formatted string here
}
Any suggestions?
That should work;
// create `Date` from date string
let dateStr = "07September16 4:09 am"
let dateFormatterGet = DateFormatter()
dateFormatterGet.locale = Locale(identifier: "en_US_POSIX")
dateFormatterGet.dateFormat = "ddMMMMyy h:mm a"
let date = dateFormatterGet.date(from: dateStr)
// convert back Date to string as Sep 07 2016
let dateFormatterPrint = DateFormatter()
dateFormatterPrint.dateFormat = "MMM dd yyyy"
print(dateFormatterPrint.string(from: date!))
let dateString = "07September16 4:09 am"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "ddMMMyy h:mm a"
let dateObj = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "MMM dd yyyy"
print("Dateobj: \(dateFormatter.string(from: dateObj!))")
First you must get date from your string with current format like`
let dateStr = dateString
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "ddMMMMyy h:mm a"
let formattedDate = dateFormatter.date(from: dateStr)!
print("formattedDate \(formattedDate)")
After getting the date you can get date string in which format you want just change the format`
dateFormatter.dateFormat = "MMM dd YYYY"
let convertedDateString = dateFormatter.string(from: formattedDate)
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 have a string that is a date in this format 03/02/2017
I would like to display it like this Mar 2, 2017
I've been trying to get this formatter to work, but it keeps giving me nil, and I don't think I'm setting it in the correct format.
// convert saved date from string
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "mm/dd/yyyy" //Your date format
let date = dateFormatter.date(from: '03/02/2017')
print("\(date) save date") // nil
historyEntry.date = date as NSDate?
is not in
dateFormatter.dateFormat = "mm/dd/yyyy"
it is in
dateFormatter.dateFormat = "MM/dd/yyyy"
for full output
let dateFormatter = DateFormatter()
// iinitiallly set the date format based on your date
dateFormatter.dateFormat = "MM/dd/yyyy" //Your date format
// convert the string to date , but date is not the proper format , so dont worry about this
let date = dateFormatter.date(from: "03/02/2017")
// again reassign what the output you need set the date format
dateFormatter.dateFormat = "MMM dd, yyyy" // if you need the same as Mar 2, 2017 then use "MMM d, yyyy"
// finally convert your date to string
let myStringafd = dateFormatter.string(from: date!)
print("\(myStringafd) save date")
output
let dateString = "03/02/2017"
let df = DateFormatter()
df.dateFormat = "MM/dd/yyyy" // this dateformat should be your current string's date format
df.timeZone = TimeZone(identifier: "UTC-05:00") // if there is timezone you want to set
if let date = df.date(from: dateString) {
df.dateFormat = "MMM dd, yyyy" // This dateformat is that you want as result
let stringFromDate = df.string(from: date)
cell.lblDate.text = stringFromDate
}
if I choose date like let dateString = "2014-01-12", How would I convert string to
dateFormatter.dateFormat = "yyyy-MM-dd"
and then in below format
dateFormatter.dateFormat = "dd-MM-yyyy"
I get nil values in Xcode 8 in Swift 3.0
{
let dateString = "2014-01-12"
dateFormatter.locale = Locale(identifier:"ja_JP")
dateFormatter.dateFormat = "dd-MM-yyyy"
print(dateFormatter.date(from:dateString))
}
or
let dateString = "2014-01-12"
dateFormatter.dateFormat = "yyyy-MM-dd"
var s = dateFormatter.date(from: dateString)! as Date
dateFormatter.dateFormat = "dd-MM-yyyy"
s = dateFormatter.date(from: dateString)! as Date
print("SecondDate\(s)")
In Xcode 7 it works fine.
If you want to convert to date formate yyyy-MM-dd to dd-MM-yyyy then your last line should be.
let dateString = "2014-01-12"
dateFormatter.dateFormat = "yyyy-MM-dd"
var s = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "dd-MM-yyyy"
Get formatted date like this
let dateStr = dateFormatter.string(from: s)
Instead of
s = dateFormatter.date(from: dateString)! as Date
You need to just change format of DateFormatter and get it as the String.
Need to change date string into "date string" as Date then you can change into your particular format. For every format you need to do this first.
You can use the code below.
Swift 3
extension String {
func changeDate(_ mydate:String) -> String {
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = DateFormatter.Style.long
dateFormatter.dateFormat = "yyyy-MM-dd"
let convertedDate = dateFormatter.date(from: mydate)
dateFormatter.dateFormat = "dd-MM-yyyy"
let date = dateFormatter.string(from: convertedDate!)
return date
}
}
You can use this
let dateString = "2014-01-12"
let dateFormatterNew = DateFormatter()
dateFormatterNew.dateFormat = "yyyy-MM-dd"
let date = dateFormatterNew.date(from: dateString)! as Date
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dateNew = dateFormatter.string(from: date )
print(dateNew)
do it like this
let datestring = "2014-01-12"
let dateF = NSDateFormatter()
dateF.dateFormat = "yyyy-MM-dd"
let firstDate = dateF.dateFromString(datestring)
dateF.dateFormat = "dd-MM-yyyy"
let newDateString = dateF.stringFromDate(firstDate!)
print("NEW DATE FORMAT IS : \(newDateString)")
From response I have set time in String, its contains HH: mm format the task is I have to convert that string into 12hrs time interval with AM and PM in another string to display results
For example "16:36:00.000Z" I want my result like 4:36 PM
Here my sample code:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let date = dateFormatter.dateFromString(dateValue)
// To convert the date into an HH:mm format
dateFormatter.dateFormat = "HH:mm"
let dateString = dateFormatter.stringFromDate(date!)
print(dateString)
But unfortunately I'm getting nil in date
do like
let dateFormatter = NSDateFormatter()
16:36:00.000Z
dateFormatter.dateFormat = "HH:mm:ss.sssZ"
let date = dateFormatter.dateFromString(dateValue)
// To convert the date into an HH:mm format
dateFormatter.dateFormat = "hh:mm a" // or //h:mm a
let dateString = dateFormatter.stringFromDate(date!)
print(dateString)
