Swift 5 getting last day of month - base on different sources

// -------------------------------------------------------
// lastDayOfMonth
// -------------------------------------------------------
static func lastDayOfMonth(year:Int, month:Int) -> Int {
    let calendar:Calendar = Calendar.current
    var dc:DateComponents = DateComponents()
    dc.year = year
    dc.month = month + 1
    dc.day = 0
    let lastDateOfMonth:Date = calendar.date(from:dc)!
    let lastDay = calendar.component(Calendar.Component.day, from: lastDateOfMonth)
    return lastDay
}
