How to get all days in current week in swift

To get the weekdays of the week, it is:

let calendar = Calendar.currentlet today = calendar.startOfDay(for: Date())let dayOfWeek = calendar.component(.weekday, from: today)let weekdays = calendar.range(of: .weekday, in: .weekOfYear, for: today)!let days = (weekdays.lowerBound ..< weekdays.upperBound)    .compactMap { calendar.date(byAdding: .day, value: $0 - dayOfWeek, to: today) }  // use `flatMap` in Xcode versions before 9.3    .filter { !calendar.isDateInWeekend($0) }

To display that as "Thursday = 82", it is

let formatter = DateFormatter()formatter.dateFormat = "eeee' = 'D"for date in days {    print(formatter.string(from: date))}

Or

let strings = days.map { formatter.string(from: $0) }

I had problems with adapting Rob's solution for when the week starts on Monday. This solution adapts to your calendar.firstWeekday setting.

var calendar = Calendar.autoupdatingCurrentcalendar.firstWeekday = 2 // Start on Monday (or 1 for Sunday)let today = calendar.startOfDay(for: Date())var week = [Date]()if let weekInterval = calendar.dateInterval(of: .weekOfYear, for: today) {    for i in 0...6 {        if let day = calendar.date(byAdding: .day, value: i, to: weekInterval.start) {            week += [day]        }    }}return week

I made a small extension on Calendar, which might be helpful for anyone else looking for a more functional solution to this.

import Foundationextension Calendar {  func intervalOfWeek(for date: Date) -> DateInterval? {    dateInterval(of: .weekOfYear, for: date)  }  func startOfWeek(for date: Date) -> Date? {    intervalOfWeek(for: date)?.start  }  func daysWithSameWeekOfYear(as date: Date) -> [Date] {    guard let startOfWeek = startOfWeek(for: date) else {      return []    }    return (0 ... 6).reduce(into: []) { result, daysToAdd in      result.append(Calendar.current.date(byAdding: .day, value: daysToAdd, to: startOfWeek))    }    .compactMap { $0 }  }}
