Convert string with timezone to date - swift

Question

I have this type of string and want to convert it to date
"2017-05-27T00:00:00.000+0400"
but none of this formatters convert it to date
"yyyy-MM-dd'T'HH:mm:SSSZ"
"yyyy-MM-dd'T'HH:mm:SSSX"

Answer 1

Your forgot to add ss for seconds so correct formate should be yyyy-MM-dd'T'HH:mm:ss.SSSZ
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let date = dateFormatter.date(from: "2017-05-27T00:00:00.000+0400")

Answer 2

Your error was that the seconds were missing. So the right format should be: yyyy-MM-dd'T'HH:mm:ss.SSSZ. You can also use an extension for this purpose:
extension String {
var toCustomDate: Date {
return Date.Formatter.customDate.date(from: self)!
}
}
extension Date {
struct Formatter {
static let customDate: DateFormatter = {
let formatter = DateFormatter()
formatter.locale = Locale(identifier: "en_US_POSIX")
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
return formatter
}()
}
var customDate: String {
return Formatter.customDate.string(from: self)
}
}
let str = "2017-05-27T00:00:00.000+0400"
let date = str.toCustomDate
If you have more date formats, then just add them to the extensions.

Answer 3

you can do like this
let dateString = "2017-05-27T00:00:00.000+0400"
let formachanger = DateFormatter()
formachanger .dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
if let dateFromString = formachanger .date(from: dateString) {
formachanger .dateFormat = "yyyy-MM-dd HH:mm"
let stringFromDate = formachanger .string(from: dateFromString)
}

Answer 4

try this function
func getGMTDateFrom(String string : String) -> Date? {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "EEE, dd MMM yyyy hh:mm:ss zz"
let dateObj = dateFormatter.date(from: string)
return dateObj
}
Change date format according to your need.
