How to change year in Date in Swift

[onmyway133]

Today I'm trying to change the year of a Date object to 2000 in Swift.

let date = Date()

Firstly, I tried with date(bySetting:) but it does not work with past year. It simply returns nil

Calendar.current.date(bySetting: .year, value: 2000, of: date)

Secondly, I tried with dateComponents. The component.year has changed, but it calendar still returns the original date, very strange !!. No matter what timezone and calendar I use, it still has this problem

var component = calendar.dateComponents(in: TimeZone.current, from: base)
component.year = year
Calendar.current.date(from: component)

Finally, I tried to be more explicit, and it works 🎉

var component = calendar.dateComponents([.year, .month, .day, .hour, .minute, .second], from: base)
component.year = year
Calendar.current.date(from: component)

This is damn right.

I had the same issue. The problem with your second try is the component yearForWeekOfYear that stayed at the previous year. Setting it at the year you want or nil will make it work
