descriptor

TypeScript

get descriptor(): RequestDescriptor

Swift declaration

var descriptor: RequestDescriptor { get }

An enum that identifies the request and request revision.

regionOfInterest

TypeScript

get regionOfInterest(): NormalizedRect

Swift declaration

var regionOfInterest: NormalizedRect

The region of the image in which Vision will perform the request. The rectangle is normalized to the dimensions of the processed image. Its origin is specified relative to the image's lower-left corner. By default, the region of interest will be the full image.

regionOfInterest

TypeScript

set regionOfInterest(value: NormalizedRect)

Swift declaration

var regionOfInterest: NormalizedRect

setComputeDevice

TypeScript

setComputeDevice(computeDevice: (_CoreML_MLComputeDevice) | null, computeStage: ComputeStage): void

Swift declaration

mutating func setComputeDevice(_ computeDevice: MLComputeDevice?, for computeStage: ComputeStage)

Assigns a compute device for a compute stage. If the parameter `computeDevice` is `nil`, the framework removes any explicit compute device assignment and allows the framework to select the device. Configure any compute device for a given compute stage. When performing a request, the system makes a validity check. Use `supportedComputeStageDevices` to get valid compute devices for a request’s compute stages. - Parameters: - `computeDevice: `The compute device to assign to the compute stage. - `computeStage: `The compute stage.

cropAndScaleAction

TypeScript

get cropAndScaleAction(): ImageCropAndScaleAction

Swift declaration

var cropAndScaleAction: ImageCropAndScaleAction

An optional setting that tells the algorithm how to scale an input image before generating the result.

supportedRevisions

TypeScript

static get supportedRevisions(): Array<DetectLensSmudgeRequest_Revision>

Swift declaration

static var supportedRevisions: [DetectLensSmudgeRequest.Revision] { get }

The collection of revisions the request supports.

get · iOS 26.0+

revision

TypeScript

get revision(): DetectLensSmudgeRequest_Revision

Swift declaration

let revision: DetectLensSmudgeRequest.Revision

The request's configured revision.

init · iOS 26.0+

init

TypeScript

static init(revision?: (DetectLensSmudgeRequest_Revision) | null): DetectLensSmudgeRequest

Swift declaration

init(_ revision: DetectLensSmudgeRequest.Revision? = nil)

Creates a request to detect whether the camera lens has a smudge. - Parameters: - revision: The specific algorithm or implementation revision that performs the request.
