날짜 차이 구하기

        let myDateComponents = DateComponents(year: 2022, month: 3, day: 01)
        let startDate = Calendar.current.date(from: myDateComponents)!
        
        let offsetComps = Calendar.current.dateComponents([.year,.month,.day], from: startDate, to: Date())
        
        if case let (y?, m?, d?) = (offsetComps.year, offsetComps.month, offsetComps.day) {
          print("\(y)년 \(m)월 \(d)일 만큼 차이남")
        }
