ios swift datepicker done button, wrong date with interval

Question

I have set up a date picker as input view of a textfield. Date picker has a minimum date and interval minute of 15. Now it gives proper date on changing the spin in value changed delegate. But if I don't spin the picker and tap done button with default first selected, it gives only current date. I would expect it to give me the date which is displayed by default in picker. Here is the code:

class ViewController: UIViewController {

    @IBOutlet weak var timeField: UITextField!

    var datePicker:UIDatePicker!

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    @IBAction func CallPicker(sender: UITextField) {

        let datePickerView:UIDatePicker = UIDatePicker()
        datePickerView.datePickerMode = UIDatePickerMode.DateAndTime
        datePickerView.minuteInterval = 15
        datePickerView.minimumDate = NSDate()
        datePicker = datePickerView

        let toolBar = UIToolbar()
        toolBar.sizeToFit()
        let spaceButton = UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: nil, action: nil)
        let doneButton = UIBarButtonItem(title: "Done", style: .Plain, target: self, action: "doneTapped")
        toolBar.setItems([spaceButton, doneButton], animated: false)
        toolBar.userInteractionEnabled = true

        sender.inputView = datePickerView
        sender.inputAccessoryView = toolBar
        datePickerView.addTarget(self, action: Selector("datePickerValueChanged:"), forControlEvents: UIControlEvents.ValueChanged)
    }

    func doneTapped() {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateStyle = .MediumStyle
        dateFormatter.timeStyle = .MediumStyle
        timeField.text = dateFormatter.stringFromDate(datePicker.date)
        timeField.resignFirstResponder()
    }

    func datePickerValueChanged(sender: UIDatePicker) {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateStyle = .MediumStyle
        dateFormatter.timeStyle = .MediumStyle
        timeField.text = dateFormatter.stringFromDate(sender.date)
    }

}

Scenario: suppose its 8:42 now. Date picker will show 8:30 as first entry but when I tap on done button, it will only give current time which is 8:42. However it works well if I roll spin and get back to first entry.

Try using following code when date is selected

    let userDateFormate = NSDateFormatter()
    userDateFormate.dateFormat = "MMMM dd, yyyy"
    let dateString = userDateFormate.stringFromDate(date)

    dateFormate.dateFormat = "MMMM dd, yyyy"
    dateFormate.timeZone = NSTimeZone.init(forSecondsFromGMT: 0)
    let dateValue = dateFormate.dateFromString(dateString)

I also face the same issue and what I do for the workaround is to set a later time to my UIDatePicker with the help of Calender.current.dateComponents

func patchTime(){
    var components = Calendar.current.dateComponents([.hour, .minute], from: self.timePicker.date);
    components.hour = (components.hour ?? 0) + 1
    components.minute = 0

    let calendar = Calendar.current
    let date = calendar.date(from: components)
    self.timePicker.date = date!;

}

Currently I am using for timepicker but if needed for date also, the pattern will be same

you just need to set the date property of this datePicker from current date to custom and then it will work.
