在swift中了解下周的开始

import Foundation

// 获取当前日期
let currentDate = Date()

// 创建一个Calendar实例
let calendar = Calendar.current

// 获取下周的开始日期
var nextWeekComponents = DateComponents()
nextWeekComponents.weekday = calendar.firstWeekday
nextWeekComponents.weekOfYear = calendar.component(.weekOfYear, from: currentDate) + 1
nextWeekComponents.yearForWeekOfYear = calendar.component(.yearForWeekOfYear, from: currentDate)

if let nextWeekStartDate = calendar.date(from: nextWeekComponents) {
    // 格式化日期
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd"
    let nextWeekStartDateString = dateFormatter.string(from: nextWeekStartDate)
    
    print("下周的开始日期是：\(nextWeekStartDateString)")
} else {
    print("获取下周开始日期失败")
}
