I have this method that parse a string Date:
let dateFormatterGet = DateFormatter()
let stringDate = "31/01/1965"
dateFormatterGet.dateFormat = "dd-MM-yyyy"
dateFormatterGet.locale = Locale(identifier: "pt_BR")
let birthDate = dateFormatterGet.date(from: stringDate)
print(birthDate)
If Date is 31/01/1965 (January 31st), the birthDate is returning nil, but if i change the day for 30, all works fine. What is wrong here?

import Foundation
let dateFormatter = DateFormatter()
var timy = "13:25:00"
dateFormatter.dateFormat = "HH:mm:ss "
print(dateFormatter.date(from: timy))
// this gives me output of differnet time i.e Optional(2000-01-01 07:55:00 +0000)
This is the correct format to account for AM/PM:
dateFormatter.dateFormat = "h:mm:ss a"

The back end is providing me with this date-as-a-string: 2021-09-10T12:57:01.671Z
I need to convert that string to a Date using the iOS DateFormatter; and to do so I need to set the formatter's dateFormat property.
I have tried all sorts of combinations, with no luck. Specifically I am struggling with the .671Z part.
What is the correct date format to use?
You need "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'" as date format
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
guard let date = dateFormatter.date(from: self) else {
// fallback if date is not in correct format
return nil
}

NSDate timeIntervalSince1970 not working in Swift? [duplicate]

I am trying to convert timestamp to Date. But it returns wrong date.
I have a time stamp
1524637838000.0
Which returns 25-04-2018 12:00 as per this online converter
But I get wrong date when convert using my code
let date = Date(timeIntervalSince1970:1524637838000.0)
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy hh:mm"
let myDate = dateFormatter.string(from: date)
print("Date is = ",myDate)
I get
07-11-50283 12:03
as result. Is there anything wrong with my code?
your timestamp 1524637838000.0 in milliseconds, it should be in seconds, so your date initialization should be:
let date = Date(timeIntervalSince1970:(1524637838000.0/1000))

I'm trying to format a string(ex. Tue, 16 Jan 2018 | 05:34 PM) to date and then convert it back to string(ex. 2018-01-16 17:34:00) with different format by using following code.
let dateFormatterOne = DateFormatter()
dateFormatterOne.dateFormat = "E, d MMM yyy | hh:mm a"
dateFormatterOne.locale = Locale(identifier: "en_US_POSIX")
let dateFromString = dateFormatterOne.date(from: string)
let dateFormatterTwo = DateFormatter()
dateFormatterTwo.dateFormat = "yyyy-MM-dd HH:mm:ss"
let dateString = dateFormatterTwo.string(from: dateFromString!)
This seems to be working well in simulator but when I tested it on an iPod Touch running iOS 9 it doesn't give date in the first conversion so it becomes nil and crashes.
