   let thirtyDaysBeforeToday = Calendar.current.date(byAdding: .day, value: -30, to: today) {
   // today: Apr 11, 2021 at 7:14 AM
   // thirtyDaysBeforeToday: Mar 12, 2021 at 7:14 AM


   // Create a Range<Date>.
   let last30days = thirtyDaysBeforeToday..<today
    
    last30days.formatted(date: .omitted, time: .standard)
// 3/12/2021, 7:11:16 AM – 4/11/2021, 7:11:16 AM


    last30days.formatted(date: .numeric, time: .omitted)
// 3/12/2021 – 4/11/2021


    last30days.formatted(date: .abbreviated, time: .omitted)
// Mar 12 – Apr 11, 2021


    last30days.formatted(date: .long, time: .omitted)
// March 12 – April 11, 2021"


    last30days.formatted(date: .complete, time: .omitted)
// Friday, March 12 – Sunday, April 11, 2021


    last30days.formatted()
// 3/12/21, 7:14 AM – 4/11/21, 7:14 AM
}

The default date style is numeric. 省略時の日付スタイルはnumericです。
