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"

The latching switch (such as a rocker) maintains its position after being pressed or turned.

The momentary switch (such as a push button) does not maintain its position after being pressed or turned. After releasing, it goes back to its idle position.

The momentary switch (such as a push button) can distinguish and report release events.

The momentary switch (such as a push button) can distinguish and report long pressed from short presses.

The momentary switch (such as a push button) can distinguish and report double press and potentially multiple presses with more events, such as a triple press.
