# RoomAnchor The representation of a room ARKit is currently tracking. ``` struct RoomAnchor ``` ## Overview A `RoomAnchor` structure describes an approximate representation of the room’s geometry, and contains arrays with identifiers of mesh and plane anchors that the framework associates with that room. ## Topics ### Getting information about a room anchor [`var geometry: MeshAnchor.Geometry`](/documentation/ARKit/RoomAnchor/geometry) The geometry of the mesh in an anchor’s coordinate system. [`var id: UUID`](/documentation/ARKit/RoomAnchor/id) The unique identifier of this anchor. [`var isCurrentRoom: Bool`](/documentation/ARKit/RoomAnchor/isCurrentRoom) A Boolean value that indicates whether a room is a person’s current location. [`var meshAnchorIDs: [UUID]`](/documentation/ARKit/RoomAnchor/meshAnchorIDs) An array of IDs of the mesh anchors associated with a room. [`var originFromAnchorTransform: simd_float4x4`](/documentation/ARKit/RoomAnchor/originFromAnchorTransform) The transform from the room anchor to the origin coordinate system. [`var planeAnchorIDs: [UUID]`](/documentation/ARKit/RoomAnchor/planeAnchorIDs) An array of IDs of the plane anchors associated with a room. ### Inspecting a room anchor [`func contains(SIMD3) -> Bool`](/documentation/ARKit/RoomAnchor/contains(_:)) Returns a Boolean value that indicates whether a room contains the provided point. [`func geometries(of: MeshAnchor.MeshClassification) -> [MeshAnchor.Geometry]`](/documentation/ARKit/RoomAnchor/geometries(of:)) Returns the disjoint mesh geometries of a given classification. [`var description: String`](/documentation/ARKit/RoomAnchor/description) A textual representation of this anchor. ### Operators [`static func == (RoomAnchor, RoomAnchor) -> Bool`](/documentation/ARKit/RoomAnchor/==(_:_:)) Returns a Boolean value indicating whether two room anchors are equal. ### Instance Methods [`func geometries(classifiedAs: SurfaceClassification) -> [MeshAnchor.Geometry]`](/documentation/ARKit/RoomAnchor/geometries(classifiedAs:)) Get disjoint mesh geometries of a given surface classification. ### Default Implementations [ARKitCoordinateSpaceProviding Implementations](/documentation/ARKit/RoomAnchor/ARKitCoordinateSpaceProviding-Implementations) ## Relationships ### Conforms To [`ARKitCoordinateSpaceProviding`](/documentation/ARKit/ARKitCoordinateSpaceProviding) [`Escapable`](/documentation/Swift/Escapable) [`Copyable`](/documentation/Swift/Copyable) [`Equatable`](/documentation/Swift/Equatable) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`Anchor`](/documentation/ARKit/Anchor) [`Sendable`](/documentation/Swift/Sendable) [`Identifiable`](/documentation/Swift/Identifiable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) --- Copyright © 2026 Apple Inc.
