Error message:

unexpected number of calendar units: 4 for format: EEE ├'day': d┤ HH.mm (expecting at least 5 elements)

Could you show how you have defined format ?

You should have something like this:

let source = "Mon, 21 Mar 2016 10:26:45 GMT"
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US")
dateFormatter.dateFormat = "EEE, dd MMM yyyy HH:mm:ss zzz"
let day = dateFormatter.date(from: source)
print("day", day!)

Or (with just 5 components):

let source = "Thu, 14 Oct 2021 10:26:45"
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US")
dateFormatter.dateFormat = "EEE, dd MMM yyyy HH:mm:ss"
let day = dateFormatter.date(from: source2)
print("day", day!)

Take care that the 3 letters for the day of week must correspond to locale:

"Thu" if "en_US"
"Jeu" if "fr_FR"
"Jue" if "es_ES"

It crashes otherwise.

This is my code, I don't have set dateFormatter.

- (UIDatePicker *)datePicker
{
  if (!_datePicker) {
    _datePicker = [[UIDatePicker alloc] initWithFrame:CGRectZero];
    if (@available(iOS 13.4, *)) {
      _datePicker.preferredDatePickerStyle = UIDatePickerStyleWheels;
    }
    NSDate *date = [NSDate date];
    _datePicker.locale = [NSLocale currentLocale];
    [_datePicker setDatePickerMode:UIDatePickerModeDate];       // crash
    [_datePicker setMaximumDate:date];
  }
  return _datePicker;
}
