UIDatePicker setting minimum and maximum hour

Question

How to set minimum and maximum hour to UIDatePicker ? At all is it possible ?

I know how to set minimum and maximum date:

[datePicker setMinimumDate: today];

Answer 1

This works in "TIME MODE", otherwise selected answer should work unintuitively though

    // minimum time
    components.hour = 0
    components.minute = 0
    let minTime = calendar.date(from: components)

    // max time
    components.hour = 23
    components.minute = 59
    let maxTime = calendar.date(from: components)

    // selected value current time or saved time
    let selectedDate = Date() // or saved time
    let nowComp = calendar.dateComponents([.hour, .minute], from: selectedDate)
    components.hour = nowComp.hour
    components.minute = nowComp.minute
    let selectedTime = calendar.date(from: components)!

play with the values and use as below

    datePicker.datePickerMode = .time
    datePicker.date = selectedTime 
    datePicker.minimumDate = minTime 
    datePicker.maximumDate = maxTime
