As today is Friday, which is 6 according to NSCalendar. I can get this by using the following
Calendar.current.component(.weekday, from: Date()) How do I get weekday component of Saturday last week, which should be 7?
If I do Calendar.current.component(.weekday, from: Date()) - 6 . I am getting 0 which is not valid component.
Try this, you have to get the date first then subtract again from it:
var dayComp = DateComponents(day: -6) let date = Calendar.current.date(byAdding: dayComp, to: Date()) Calendar.current.component(.weekday, from: date!) For that first you need to get that date using calendar.date(byAdding:value:to:) and then get day number from it.
extension Date { func getDateFor(days:Int) -> Date? { return Calendar.current.date(byAdding: .day, value: days, to: Date()) } } Now simply use thus function and get your days.
if let date = Date().getDateFor(days: -6) { print(Calendar.current.component(.weekday, from: date)) } you can use calendar and date components and put everything in a Date extension, something like:
(Swift 4.1)
extension Date { func removing(minutes: Int) -> Date? { let result = Calendar.current.date(byAdding: .minute, value: -(minutes), to: self) return result } }
