Answer 1

first change the version checking line to

if #available(iOS 13.4,*) {

}

secondly use calendar for min max date

        let datePicker = UIDatePicker()
        if let eighteenAgo = Calendar.current.date(byAdding: .year, value: -18, to: Date()),
           let afterFiftyFive =  Calendar.current.date(byAdding: .year, value: 55, to: Date()) {
            print(eighteenAgo.formatted(), ": Min")
            print(afterFiftyFive.formatted(), ": Max")
            datePicker.minimumDate = eighteenAgo
            datePicker.maximumDate = afterFiftyFive
        }
