Упорядочение массива дат от самых последних до самых старых, при этом изменяя другие массивы в соответствии с порядком

/ 14 февраля 2019

У меня есть массив дат, чтобы пойти вместе с двумя другими массивами строк.Я пытаюсь выяснить, как переупорядочить массив дат с самых последних до самых старых.Кроме того, при изменении порядка массива дат два других массива необходимо изменить в том же порядке, что и массивы дат.

Вот массивы

Дневной класс 

class Day {
    var date: Date

        self.sleep = sleep

Глядя на ваш код, ошибка заключается в наличии дополнительных массивов (даты, сны и время загрузки).Массив дней - это все, что вам нужно.Если вы хотите заказать его, просто отсортируйте дни: 

let sortedDays = days.sorted(by: { $0.date < $1.date} )

Тогда вы можете делать все, что вам нужно, с sortedDays.Если для какой-то конкретной проблемы вам нужен список только дат или просто снов, вы можете получить его в любое время, когда вам это нужно, с помощью map: 

let dates = sortedDays.map { $0.date }
