SwiftUI DatePicker Styles: Automatic, Compact, and Wheel

The 'preferredDatePickerStyle' property in SwiftUI is used to control the visual style of the date picker. You can choose from three options: 'automatic', 'compact', and 'wheel'.

• 'automatic': This style automatically adapts to the platform and available screen space. It defaults to 'wheel' on iOS 14+ and macOS 11+, while opting for 'compact' on older versions.

• 'compact': This style presents a compact date picker, ideal for scenarios where space is limited, like within a toolbar or navigation bar.

• 'wheel': This style features a wheel-like interface, allowing users to scroll through available date options. It's the default style on iOS 14+ and macOS 11+.

Example Usage:

DatePicker('Select Date', selection: $selectedDate)
    .preferredDatePickerStyle(.wheel)
