How to find out what first day of week is? (Monday or Sunday)

I want to check if the first day of the week for a user is Monday or Sunday to perform some actions with the calendar. Is it possible to determinate that using NSCalendar or any other way?

You can just use the firstWeekday property…

var calendar = Calendar.current

calendar.locale = Locale(identifier: "en_GB")
print("\(calendar.locale!) starts on day \(calendar.firstWeekday)")
// en_GB starts on day 2

calendar.locale = Locale(identifier: "en_US")
print("\(calendar.locale!) starts on day \(calendar.firstWeekday)")
// en_US starts on day 1

update

Per @maddy's comment below, Calendar.current will have the correct locale set for the current user.

let calendar = Calendar.current
print("\(calendar.locale!) starts on day \(calendar.firstWeekday)")
// en_GB starts on day 2 (in my case)

It's just:

Swift:

Calendar.current.firstWeekday

Obj-C:

[NSCalendar currentCalendar].firstWeekday

With 1 = Sunday.
