uitextview - How to use UIDatePicker in Mac app (macCatalyst)?

Question

I have compatible my iOS app to Mac App. Where I used UIDatePicker to select date. This works fine for all iOS devices but its not working for Mac.

Code :

UIDatePicker *datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
if (@available(iOS 14.0, *)) {
    datePicker.preferredDatePickerStyle = UIDatePickerStyleWheels;
}
txtView.delegate= self;
txtView.inputView = datePicker;
txtView.inputAccessoryView = [self createDatePickerToolBar];

Can anyone have any idea what's wrong or change required to get it done on Mac catalyst?

Thanks!
