Summary:
The propTypes of RCTDatePickerIOS do not fit with the propTypes of DatePickerIOS.
All dates (date, minimumDate, maximumDate) are a timestamp (check line 126), so they should have propType number.
OnDateChange function should not be required since it is called onChange in the iOS implementation.
The problem currently causes warnings that the given types are wrong, while they were added correctly.
