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.

score
TypeScript
get score(): number
Swift declaration
let score: Float
A value that indicates the quality of the face capture.
The score allows you to compare the quality of the face in terms of its capture attributes: lighting,
blur, and prime positioning. Use this value to compare the capture quality of a face against other captures of the same
face in a specified set. The value of this property value ranges from `0.0` to `1.0`. Faces with quality closer to `1.0`
are better lit, sharper, and more centrally positioned than faces with quality closer to `0.0`.
