Summary:
UIDatePicker when I give it calendar with islamicUmmAlQura it gives me a strange behaviour. The days starts from 1 to 30 but there is a '2' above 1 and below 30 such that days are as follows 2,1,2,3,4 ... 30 this strange behaviour occurs with all months.

Please see attached screenshots.

Steps to Reproduce:
1. Create Single View Application for iOS project with any XCode version.
2. Paste the following code inside viewDidLoad method for your ControllerView class.
3. Run the app in Simulator or iPhone device.
4. Scroll to first day of any months in the UIDatePicker

The code to be pasted:
let picker = UIDatePicker(frame: CGRect(x: 0, y: 30, width: 0, height: 0))

picker.datePickerMode = .date
picker.date = Date()
picker.calendar = Calendar(identifier: .islamicUmmAlQura)
picker.autoresizingMask = UIViewAutoresizing.flexibleRightMargin
picker.frame.size.width = 300
view.addSubview(picker)

Expected Results:
For each month in the UIDatePicker, days should start from 1 ... 29 or 30 as per all islamic calendars. (1, 2, 3, 4, 5 ... 29 or 30)
