In Swift, how to delete hours in a Date object? - swift

Question

i need to use a dictionary of dates, and i need to delete all the information about a date except:
day
month
year
i create this static function:
let day = Date() // it's an example
print(day)
func dateSimplificator(WithDate date: Date) -> Date {
let formatterD = DateFormatter()
formatterD.dateFormat = "dd MM yyyy"
let dayString = formatterD.string(from: date)
let reFormatterD = DateFormatter()
reFormatterD.dateFormat = "dd MM yyyy"
let dayFormatted = reFormatterD.date(from: dayString)!
//print(dayFormatted)
return dayFormatted
}
print(dateSimplificator(WithDate: day))
and when i print, i obtain:
2020-09-03 10:40:25 +0000
2020-09-02 23:00:00 +0000
it isn't what i want.
I need somthing like this:
the date => 2020-09-03 10:40:25 +0000
and when i use the static function with the date, i have to obtain a new date like this :
2020-09-02 00:00:00 +0000
what should a change in my function?

Answer 1

First of all your method can be written without a date formatter
func dateSimplificator(with date: Date) -> Date {
return Calendar.current.startOfDay(for: date)
}
Second of all a date formatter considers the local time zone – which is clearly UTC+0100 in your case – but print shows dates in UTC. 2020-09-03 00:00:00 +0100 and 2020-09-02 23:00:00 +0000 is the same moment in time.
