  ` Creates a new instance with the specified raw value.

  If there is no value of the type that corresponds with the specified raw
  value, this initializer returns `nil`. For example:

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

      print(PaperSize(rawValue: "Legal"))
      // Prints "Optional(PaperSize.Legal)"

      print(PaperSize(rawValue: "Tabloid"))
      // Prints "nil"

  #### Declaration

  Swift

      init?(rawValue: UInt64)

  #### Parameters

  |---|---|
  | ` rawValue ` | The raw value to use for the new instance. |
