A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an
instance of any type to a string by using the `String(describing:)`
initializer. This initializer works with any type, and uses the custom
`description` property for types that conform to
`CustomStringConvertible`:
struct Point: CustomStringConvertible {
let x: Int, y: Int
var description: String {
return "(\(x), \(y))"
}
}
let p = Point(x: 21, y: 30)
let s = String(describing: p)
print(s)
// Prints "(21, 30)"
The conversion of `p` to a string in the assignment to `s` uses the
`Point` type's `description` property.

initStringLiteral(value: string): LaunchTaskID
Swift declaration
init(stringLiteral value: String)
Creates an instance initialized to the given string value.
- Parameter value: The value of the new instance.

TypeScript
initRawValue(rawValue: string): LaunchTaskID
Swift declaration
init(rawValue: String)
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"
- Parameter rawValue: The raw value to use for the new instance.

rawValue
TypeScript
getRawValue($self: LaunchTaskID): string
Swift declaration
let rawValue: String
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"
