# CapturedRoom.Object A 3D area in a room that the framework identifies as an object. ``` struct Object ``` ## Overview A captured room contains an array of this type for the objects ([`objects`](/documentation/RoomPlan/CapturedRoom/objects)) it identifies. ## Topics ### Creating an object [`init(from: any Decoder) throws`](/documentation/RoomPlan/CapturedRoom/Object/init(from:)) Creates an object by deserializing the specified decoder. ### Identifying an object [`var identifier: UUID`](/documentation/RoomPlan/CapturedRoom/Object/identifier) A unique alphanumeric value that the framework assigns the object. [`var parentIdentifier: UUID?`](/documentation/RoomPlan/CapturedRoom/Object/parentIdentifier) A unique alphanumeric value that identifies the object’s parent object or surface. [`var category: CapturedRoom.Object.Category`](/documentation/RoomPlan/CapturedRoom/Object/category-swift.property) A classification that the captured room assigns the object. [`enum Category`](/documentation/RoomPlan/CapturedRoom/Object/Category-swift.enum) Classifications of an object in a captured room. [`var confidence: CapturedRoom.Confidence`](/documentation/RoomPlan/CapturedRoom/Object/confidence) A level of certainty in the object’s category. ### Positioning and sizing an object [`var transform: simd_float4x4`](/documentation/RoomPlan/CapturedRoom/Object/transform) A matrix that defines the object’s position and orientation in the room. [`var dimensions: simd_float3`](/documentation/RoomPlan/CapturedRoom/Object/dimensions) A bounding box sized to the object’s extremities. [`var story: Int`](/documentation/RoomPlan/CapturedRoom/Object/story) The floor number or level on which the object resides. ### Describing an object [`var attributes: [any CapturedRoomAttribute]`](/documentation/RoomPlan/CapturedRoom/Object/attributes) A collection of details that describe a particular object in the room. [`func attribute(of: T.Type) -> T?`](/documentation/RoomPlan/CapturedRoom/Object/attribute(of:)) Checks an object for specific attribute types. ### Serializing an object [`func encode(to: any Encoder) throws`](/documentation/RoomPlan/CapturedRoom/Object/encode(to:)) Serializes an object to the specified encoder. ## Relationships ### Conforms To [`Sendable`](/documentation/Swift/Sendable) [`Decodable`](/documentation/Swift/Decodable) [`Encodable`](/documentation/Swift/Encodable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) --- Copyright © 2026 Apple Inc.
