    dateFormtter.dateFormat = "MM/dd/yyyy"

    let startDate = dateFormtter.date(from: startDateString)
    let endDate = dateFormtter.date(from: endDateString)

    var arrYears = [String]()
    dateFormtter.dateFormat = "MM"

    if let startYear: Int = startDate?.year(), let endYear = endDate?.year() {
        for i in startYear...endYear {
            let monthWithYear = "\(i)"

        }
    }
