init

TypeScript

static initUuidString(string: string): (string) | null

Swift declaration

init?(uuidString string: String)

Creates a UUID from a string representation. Returns `nil` if the string isn't a valid UUID representation. - Parameter string: The string representation of a UUID, such as `E621E1F8-C36C-495A-93FC-0C247A3E6E5F`.

uuidString

TypeScript

get uuidString(): string

Swift declaration

var uuidString: String { get }

Returns a string created from the UUID, such as "E621E1F8-C36C-495A-93FC-0C247A3E6E5F".

description

TypeScript

get description(): string

Swift declaration

var description: String { get }

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.

customMirror

TypeScript

get customMirror(): SDKHandle

Swift declaration

var customMirror: Mirror { get }

The custom mirror for this instance. If this type has value semantics, the mirror should be unaffected by subsequent mutations of the instance.

debugDescription

TypeScript

get debugDescription(): string

Swift declaration

var debugDescription: String { get }

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

init

TypeScript

static initUuid(uuid: [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number]): string

Swift declaration

init(uuid: uuid_t)

Creates a UUID from the uuid C-language structure. - Parameter uuid: The C-language structure of a UUID.

uuid

TypeScript

get uuid(): [number, number, number, number, number, number, number, number, number, number, number, number, number, number, number, number]

Swift declaration

var uuid: (UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8, UInt8) { get }

Returns the UUID as bytes.

init

TypeScript

static init(): string

Swift declaration

init()

Creates a UUID with RFC 4122 version 4 random bytes.
