Initializer

init(rawValue:)

Creates a new instance with the specified raw value.

init?(rawValue: Int8)

Parameters

rawValue: The raw value to use for the new instance.

Discussion

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"
