UIDatePicker shows 12-h time instead of 24-h time

Question

I've found some very strange behaviour in UIDatePicker: in my iPhone's settings I've select 24-h time but UIDatePickerstill shows 12-h time.

The local of UIDatePicker is default (based on user settings).

How to reproduce:

Preconditions:

• iPhone language should be English
• 24 hours format should be set
• Timezone should be set as automatic
• iPhone region: Ukraine

Steps:

1. Change iPhone language to Ukrainian(haven't tested with other languages)
2. Change timezone to Manual
3. Switch 24-h time format to 12-h
4. Switch 12-h time format to 24-h

As a result, we get the following: screenshot

Question: Is it the iOS bug or just my mistake?

Thank you for any suggestions.

You can set the locale to auto update based on the user preferences like this

let datePicker = UIDatePicker()
datePicker.locale = Locale.autoupdatingCurrent
