在swift中按给定时间对最接近的日期进行排序

import Foundation

// 1. 创建包含日期的数组
let dates: [Date] = [
    Date(), // 当前日期
    // 其他日期...
]

// 2. 计算日期之间的时间差
let calendar = Calendar.current

func calculateTimeDifference(from fromDate: Date, to toDate: Date) -> TimeInterval {
    let components = calendar.dateComponents([.year, .month, .day, .hour, .minute, .second], from: fromDate, to: toDate)
    let timeDifference = calendar.date(from: components)?.timeIntervalSince(fromDate) ?? 0
    return timeDifference
}

// 3. 创建自定义排序函数
func sortByClosestDate(_ date1: Date, _ date2: Date) -> Bool {
    let currentDate = Date() // 当前日期
    let timeDifference1 = calculateTimeDifference(from: date1, to: currentDate)
    let timeDifference2 = calculateTimeDifference(from: date2, to: currentDate)
    return timeDifference1 < timeDifference2
}

// 4. 使用自定义排序函数对日期数组进行排序
let sortedDates = dates.sorted(by: sortByClosestDate)
