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"

Use vendor-specific temperature levels.

Use actual temperature numbers, in Celsius.

Use step control with temperature numbers. This feature is for devices that support discrete temperature setpoints that are larger than the temperature resolution imposed by the temperature data type.
