这个问题已经在 SO 上得到了回答。这是参考：

iOS 通知触发器：每两周和/或每季度一次

但到目前为止我已经尝试过：

var fortnightPart1 = DateComponents()
fortnightPart1.weekday = Calendar.current.component(.day, from: Sdate) //(Day..here Sunday)
fortnightPart1.weekdayOrdinal = 2 //= n == (nth Day in the month...here 2nd Sunday in every month month)
fortnightPart1.hour = Calendar.current.component(.hour, from: Sdate)
fortnightPart1.minute = Calendar.current.component(.minute, from: Sdate)
fortnightPart1.second = Calendar.current.component(.second, from: Sdate)
trigger = UNCalendarNotificationTrigger(dateMatching: fortnightPart1, repeats: repeate)

我无法在 14 天后实现它。虽然，它来自一个随机数据。任何人都可以检查代码有什么问题吗？

更新：

根据您的建议（/sf/answers/3225074821/），这是最终有效的代码！

//for 1st time notification
 let center = UNUserNotificationCenter.current()
 let content = UNMutableNotificationContent()
 content.title = title
 content.body = body …
