New Feature

Weekly Do Not Disturb (Weekly DND)

• Users can now set weekly do not disturb schedules.
• Users can set different DND time windows for each day of the week, that is to be repeated weekly.
• This new feature replaces the legacy daily DND interfaces, which are now deprecated (see deprecated interfaces below).
  • setWeeklyDoNotDisturb(schedules:timezone:completionHandler:) — set per-day DND schedules with multiple time windows per day
  • getWeeklyDoNotDisturb(completionHandler:) — retrieve the current weekly DND schedules
  • clearWeeklyDoNotDisturb(completionHandler:) — clear all weekly DND schedules
  • DndSchedule as a typealias for [DayOfWeek: [DndTimeWindow]]

// USAGE EXAMPLE:

// Using a factory method
let schedule: DndSchedule = .weekdays([
    DndTimeWindow(startHour: 22, startMinute: 0, endHour: 23, endMinute: 59)
])

// Using a dictionary literal
let schedule: DndSchedule = [
    .monday: [DndTimeWindow(startHour: 9, startMinute: 0, endHour: 17, endMinute: 0)],
    .saturday: [DndTimeWindow(startHour: 0, startMinute: 0, endHour: 12, endMinute: 0)]
]

// Pass to setWeeklyDoNotDisturb
SendbirdChat.setWeeklyDoNotDisturb(schedules: schedule, timezone: .current) { error in
    // Handle error
}
