struct Landmarks2D

A collection of facial features that a request detects. This class represents the set of all detectable 2D face landmarks and regions, exposed as properties. The coordinates of the face landmarks are normalized to the dimensions of the face observation’s `boundingBox`, with the origin at the bounding box’s lower-left corner.

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.
