    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.
