show date and time separately in Swift - ios

Question

Trying to show the time and date separately in Swift 3 and both fields are returning nil. I'm receiving the date as a string thats in the standard Date() format.
public func formatDateForAbandonTicket(_ dte: String) -> String {
print(dte)
let timeFormatter = DateFormatter()
timeFormatter.dateFormat = "HH:mm"
let t = timeFormatter.date(from: dte)
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "d/MM/YYYY"
dateFormatter.timeZone = TimeZone(abbreviation: "GMT+0:00")
let d = dateFormatter.date(from: dte)
print()
print(t)
print()
print(d)
return "\(d)" + " " + "\(t)"
}
I get a nil response from both d & t. The parameter does contain the right date "2017-11-14 16:36:29 +0000".
Thanks

Your code doesn't work because you need to first convert dte to a Date and to do that, you need to specify a format that matches the complete date string. You only need one Date, not two.
And there is no reason to create two separate strings just to combine them back into one.
public func formatDateForAbandonTicket(_ dte: String) -> String {
print(dte)
let df = DateFormatter()
df.dateFormat = "yyyy-MM-dd HH:mm:ss Z"
df.locale = Locale(identifier: "en_US_POSIX")
if let date = df.date(from: dte) {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "d/MM/yyyy HH:mm"
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
let dateStr = dateFormatter.string(from: date)
return dateStr
} else {
return ""
}
}
Also note that you are converting the result to a time in UTC time instead of the user's locale time. That's fine if that is what you need, just make sure it makes sense to the user.
