Restricting enabled time to a specific time span in UIDatePicker swift 4

I'm trying to restrict the time of a datePicker from 09:00 AM to 09:00 PM (21:00) with a time interval of 30 minutes. I have tried all known means for that and have been searching the internet for a long time. But I found nothing. Here is the code I wrote 

//datePicker.setDate(dateFormatter.date(from: "09.00")!, animated: true)
datePicker.maximumDate = Calendar.current.date(byAdding: .hour, value: -12, to: dateFormatter.date(from: "21.00")!) //)Calendar.current.date(byAdding: Calendar.Component.hour, value: 1, to: Date())
 datePicker.minimumDate = Calendar.current.date(byAdding: Calendar.Component.hour, value: -12, to: dateFormatter.date(from: "09.00")!)

But it didn't work. Please help.

Restricting user so she/he can only pick date between 9 and 12 but will show all the available options as this is date picker view's default behaviour but by setting proper minimumDate and maximumDate user can only pick between 9 and 21. Try below code and let me know if it works

And if you want to display times of your choice I will suggest better create an array of times you want to display, So user will only choose from the array you will provide In this case times between 9 am and 9 pm like [9:00,9:30,10:00,10:30,.....,21:00] and set that array to normal picker 

datePicker.datePickerMode = .time // setting mode to timer so user can only pick time as you want 
datePicker.minuteInterval = 30  // with interval of 30 
let dateFormatter = DateFormatter()
dateFormatter.dateFormat =  "HH:mm"

let min = dateFormatter.date(from: "9:00")      //createing min time
let max = dateFormatter.date(from: "21:00") //creating max time
datePicker.minimumDate = min  //setting min time to picker
datePicker.maximumDate = max  //setting max time to picker

Try this:

let now = Date()
datePicker.datePickerMode = .time
datePicker.minimumDate = Calendar.current.date(bySettingHour: 9, minute: 0, second: 0, of: now)
datePicker.maximumDate = Calendar.current.date(bySettingHour: 21, minute: 0, second: 0, of: now)
datePicker.minuteInterval = 30

Did you try to achieve this from storyboard?

try following configuration: enter image description here

from code:

let calendar = Calendar.current
var dateComponents = calendar.dateComponents([.day, .month, .year], from: Date())
dateComponents.setValue(9, for: .hour)
let minDate = Calendar.current.date(from: dateComponents)
dateComponents.setValue(21, for: .hour)
let maxDate = Calendar.current.date(from: dateComponents)

self.datePicker?.minimumDate = minDate
self.datePicker?.maximumDate = maxDate
self.datePicker?.minuteInterval = 30

The values you want to put in minimumDate and maximumDate are 9am and 9pm of the current date. The current date is what is missing in your code

let cal = Calendar.current
let now = Date()  // get the current date and time (2018-03-27 19:38:44)
let components = cal.dateComponents([.day, .month, .year], from: now)  // extract the date components 28, 3, 2018
let today = cal.date(from: components)!  // build another Date value just with date components, without the time (2018-03-27 00:00:00)
datePicker.minimumDate = today.addingTimeInterval(60 * 60 * 9)  // adds 9h
datePicker.maximumDate = today.addingTimeInterval(60 * 60 * 21) // adds 21h
