Enumerate dates between two intervals (Date/DateInRegion.dates(between:and:increment)

[artemkalinovsky]

I have idea to impelement method, that will give you Array of Date objects between two dates

static func datesBetween(startDate:Date, endDate: Date) -> [Date] 

[malcommac]

a sort of enumeration of dates; we could also give the opportunity to set a pre-defined time to apply to each enumerated date (optional maybe)

[artemkalinovsky]

I guess a pre-defined time to apply should be optional, but with default value

At the moment I've implemented it in this way:

extension Date {
    static func datesBetween(startDate:Date, endDate: Date, addingDateComponents: DateComponents) -> [Date] {
        let calendar = NSCalendar.current

        let normalizedStartDate = calendar.startOfDay(for: startDate)
        let normalizedEndDate = calendar.startOfDay(for: endDate)

        var dates = [normalizedStartDate]
        var currentDate = normalizedStartDate

        repeat {
            currentDate = calendar.date(byAdding: addingDateComponents, to: currentDate)!
            dates.append(currentDate)

        } while !calendar.isDate(currentDate, inSameDayAs: normalizedEndDate)

        return dates
    }
}

And using it:

  months = Date.datesBetween(startDate: startDate,
                                       endDate: endDate,
                                       addingDateComponents: 1.months)

Thank you, I've just added it to 4.0.8 release both for DateInRegion and Date instances.

Below an example with Date:

let from = Date().startOf(component: .day)
let to = from + 30.days
let dates = Date.dates(between: from, and: to, increment: 1.day)

It's pretty similar with DateInRegion:

let from = DateInRegion().startOf(component: .day)
let to = from + 30.days
let dates = DateInRegion.dates(between: from, and: to, increment: 1.day)

Awesome!👍👏
