问题

I'm trying to set the maximum date to be 7 days ahead of the current date ( today's date).

datePicker.maximumDate =

I've figured it out.

var sevenDaysfromNow: Date {
   return (Calendar.current as NSCalendar).date(byAdding: .day, value: 7, to: Date(), options: [])!
}

datePicker.maximumDate = sevenDaysfromNow

I think this is easier:

 datePicker.maximumDate = date.addingTimeInterval(604800)

604800 seconds are 7 days.
