# subject(at:)

Returns the subject at the given point within the interaction’s image, if one exists.

## Declaration

```swift
@MainActor final func subject(at point: CGPoint) async -> ImageAnalysisInteraction.Subject?
```

## Parameters

- `point`: A point in view coordinates at which to select a subject.

## Return Value

Return Value The subject that resides at point; or, nil, if no subject resides at point.

## Discussion

Discussion This method works for interaction types that include imageSubject. The following code retrieves a subject image given a screen point, for instance, where a person taps: let configuration = ImageAnalyzer.Configuration() ... interaction.preferredInteractionTypes = [.imageSubject] ... let viewPoint = /* A point in view coordinates */ if let subjectObject = try await interaction.subject(at: viewPoint) {     if let image = subjectObject.image {         // Do something with the subject image.     } }
