Get an Array of Dates of the current week starting on Monday

Question

I have this code currently:

public var daysOfWeek: [Date]? {

    let calendar = Calendar.current

    let today = self
    let dayOfWeek = calendar.componen         


        

Answer 1

You just need to get the first day of the week using iso8601 calendar where the first weekday is Monday and add from 0 to 6 days to it. Try like this:

extension Calendar {
    static let iso8601 = Calendar(identifier: .iso8601)
}
extension Date {
    var startOfWeek: Date {
        return Calendar.iso8601.date(from: Calendar.iso8601.dateComponents([.yearForWeekOfYear, .weekOfYear], from: self))!
    }
    var daysOfWeek: [Date] {
        let startOfWeek = self.startOfWeek
        return (0...6).compactMap{ Calendar.current.date(byAdding: .day, value: $0, to: startOfWeek)}
    }
}

Date().daysOfWeek  // ["Aug 13, 2018 at 12:00 AM", "Aug 14, 2018 at 12:00 AM", "Aug 15, 2018 at 12:00 AM", "Aug 16, 2018 at 12:00 AM", "Aug 17, 2018 at 12:00 AM", "Aug 18, 2018 at 12:00 AM", "Aug 19, 2018 at 12:00 AM"]
