Feature

The corresponding value of the raw type.

A new instance initialized with rawValue will be equivalent to this instance. For example:

enum PaperSize: String {
    case A4, A5, Letter, Legal
}

let selectedSize = PaperSize.Letter
print(selectedSize.rawValue)
// Prints "Letter"

print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!)
// Prints "true"

Creates a new option set from the given raw value.

This initializer always succeeds, even if the value passed as rawValue exceeds the static properties declared as part of the option set. This example creates an instance of ShippingOptions with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members.

let extraOptions = ShippingOptions(rawValue: 255)
print(extraOptions.isStrictSuperset(of: .all))
// Prints "true"
