I have the next string date:
"2017-01-04 15:25:37 +0000"
and now I want to convert it to Date in Swift 3:
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss Z"
dateFormatter.timeZone = TimeZone(identifier: "UTC")
let date = dateFormatter.date(from: "2017-01-04 15:25:37 +0000")
Why it 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)
How to use Date Formatter in ios 10 swift 3?

You'll have to first convert the string to a date and then to a string in your required format. You can use DateFormatter to do this. Check the below code
let date = "07-11-2016 12:00:00"
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy HH:mm:ss"
let convertedDate = formatter.date(from: date)
formatter.dateFormat = "d MMMM yyyy h a"
let dateString = formatter.string(from: convertedDate!)
print(dateString) // Output will be 7 November 2016 12 PM
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy HH:mm:ss"
let date = dateFormatter.date(from: "07-11-2016 12:00:00")
dateFormatter.dateFormat = "dd MMMM yyyy HH a"
let dateString = dateFormatter.string(from: date)
dateString will be you desired output format of you date.
or you can simply create an extension of Date or string that return you the formatted date.
I have encountered with below lines of code sometimes doesn't return proper UTC value:
let date = NSDate()
let formatter = NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZ"
formatter.timeZone = NSTimeZone(abbreviation: "UTC")
Returns:
"2016-12-11 2:07:35 am +0000"
Instead of:
"2016-12-11 02:07:35 +0000"
What's wrong with that?
please use these code
let date = NSDate()
let formatter = NSDateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZ"
formatter.timeZone = NSTimeZone.localTimeZone()
formatter.locale = NSLocale.currentLocale()
print(formatter.stringFromDate(date))
i have date string 2017-01-03T10:45:00.000+02:00 and I need to transfer it to something like this 2017-01-03 10:45:00 +0200
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
// this formatter returning 2017-01-03 08:45:00 +0000 but I need
// 2017-01-03 10:45:00 +0200
Thank you for your help!
Try this,
Swift 3.0
let dateStr = "2017-01-03T10:45:00.000+02:00"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd\'T\'HH:mm:ss\'.000\'z"
dateFormatter.timeZone = NSTimeZone(name: "UTC") as TimeZone!
let date = dateFormatter.date(from: dateStr)
print("Date from String : \(date)")
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx'"
dateFormatter.timeZone = NSTimeZone(forSecondsFromGMT: 7200) as TimeZone!
print("String From Date : \(dateFormatter.string(from: date!))")
Result:
Date from String : Optional(2017-01-03 08:45:00 +0000)
String From Date : 2017-01-03 10:45:00 +0200
This one works for me, Hope it help's you
let dateString = "2017-01-03 08:45:00 +0000"
// create dateFormatter with UTC time format
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx"
dateFormatter.timeZone = NSTimeZone(name: "UTC") as TimeZone!
let date = dateFormatter.date(from: dateString)// create date from string
print("Date1 : \(date)")
// change to a readable time format and change to local time zone
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx'"
dateFormatter.timeZone = NSTimeZone(forSecondsFromGMT: 7200) as TimeZone!
print("Date2 : \(dateFormatter.string(from: date!))")
If you want to convert String to Date try the below code and let me know,
let dateString = "2016-10-25"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"
let FormatDate = dateFormatter.dateFromString(dateString)
print(FormatDate)
More over you can get the time from below format:
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
Try this:
let dateString = "2017-01-03T10:45:00.000+02:00"
let dateFormatter = DateFormatter()
dateFormatter.timeZone = NSTimeZone(name: "UTC") as TimeZone!
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss SSSZ"
let FormatDate = dateFormatter.dateFromString(dateString)
print(FormatDate)
I know there are lot of questions passing around over this simple issue, but still I couldn't get a clear idea.
Here is what I want:
SelectedDateString = "19-08-2015 09:00 AM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy HH:mm a"
dateFormatter.timeZone = NSTimeZone();
let SelectedUTCDate = dateFormatter.dateFromString(SelectedDateString)!
println("SelectedLocalDate = \(SelectedLocalDate)")
// OUTPUT: SelectedLocalDate = 2015-08-18 18:30:00 +0000
If I dont use TimeZone:
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy HH:mm a"
// dateFormatter.timeZone = NSTimeZone();
let SelectedUTCDate = dateFormatter.dateFromString(SelectedDateString)!
println("SelectedLocalDate = \(SelectedLocalDate)")
//OUTPUT: SelectedLocalDate = 2015-08-18 19:26:00 +0000
Why is there change in the time and Date? What I want is:
//OUTPUT: SelectedLocalDate = 2015-08-19 09:00:00 +0000
Also I want to convert the Local Date to Exact UTC Date
//Like this: SelectedUTCDate = 2015-08-19 03:30:00
inputString = "19-08-2015 10:45 am" // My localtime is 10:35 AM, so I set 10 mins from now
var currentUTCTime = NSDate() // currentUTCTime is 05: 15 AM.
I want to convert the inputString to its respective UTC Time and find the difference between the two times in both date and string.
//Like this Date: diffInDate: 00-00-0000 00:10 and
// Like this String: diffInString: 10 mins
How can I get both of these?
let dateString = "19-08-2015 09:00 AM"
let dateFormatter = DateFormatter()
dateFormatter.calendar = Calendar(identifier: .iso8601)
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
dateFormatter.dateFormat = "dd-MM-yyyy hh:mm a"
if let dateFromString = dateFormatter.date(from: dateString) {
print(dateFromString) // "2015-08-19 09:00:00 +0000"
dateFormatter.timeZone = .current
dateFormatter.dateFormat = "dd-MM-yyyy hh:mm a Z"
dateFormatter.string(from: dateFromString) // 19-08-2015 06:00 AM -0300"
}
extension Date {
func originToString(dateFormat: String) -> String {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = dateFormat
dateFormatter.calendar = Calendar(identifier: .iso8601)
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
return dateFormatter.string(from: self)
}
}
