最简单的方法在iPhone上的两个NSDates之间循环？

import Foundation

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"

let startDate = dateFormatter.date(from: "2022-01-01")!
let endDate = dateFormatter.date(from: "2022-01-10")!

let calendar = Calendar.current
var currentDate = startDate

while currentDate <= endDate {
    print(dateFormatter.string(from: currentDate))
    
    guard let nextDate = calendar.date(byAdding: .day, value: 1, to: currentDate) else {
        break
    }
    currentDate = nextDate
}
