# EntityGeometricPins A structure that wraps all geometric pins an entity owns. ``` @MainActor struct EntityGeometricPins ``` ## Overview Access an instance of this structure through the entity property [`pins`](/documentation/RealityKit/Entity/pins). ## Topics ### Structures [`struct Iterator`](/documentation/RealityKit/EntityGeometricPins/Iterator) An object to iterate over all geometric pins in the collection. ### Instance Properties [`var count: Int`](/documentation/RealityKit/EntityGeometricPins/count) The total number of pins. [`let entity: Entity`](/documentation/RealityKit/EntityGeometricPins/entity) The entity where the local frame lives. [`var isEmpty: Bool`](/documentation/RealityKit/EntityGeometricPins/isEmpty) A Boolean value indicating whether the collection is empty. ### Instance Methods [`func makeIterator() -> EntityGeometricPins.Iterator`](/documentation/RealityKit/EntityGeometricPins/makeIterator()) Returns an iterator for the sequence. [`func remove(named: String)`](/documentation/RealityKit/EntityGeometricPins/remove(named:)) Removes a geometric pin with the given name from this entity. [`func set(named: String, position: SIMD3, orientation: simd_quatf) -> GeometricPin`](/documentation/RealityKit/EntityGeometricPins/set(named:position:orientation:)) Creates and adds a geometric pin to the entity, and returns the entity geometric pin. [`func set(named: String, position: SIMD3, orientation: simd_quatf, relativeTo: Entity?) -> GeometricPin`](/documentation/RealityKit/EntityGeometricPins/set(named:position:orientation:relativeTo:)) Creates and adds a geometric pin to the entity, and returns the entity geometric pin. [`func set(named: String, skeletalJointName: String, position: SIMD3, orientation: simd_quatf) -> GeometricPin`](/documentation/RealityKit/EntityGeometricPins/set(named:skeletalJointName:position:orientation:)) Creates and adds a geometric pin to the entity’s skeletal joint, and returns the geometric pin. ### Subscripts [`subscript(String) -> GeometricPin?`](/documentation/RealityKit/EntityGeometricPins/subscript(_:)) Obtains a geometric pin the entity owns by name. ### Type Aliases [`typealias Element`](/documentation/RealityKit/EntityGeometricPins/Element) An individual pin in the collection. ## Relationships ### Conforms To [`Sendable`](/documentation/Swift/Sendable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Sequence`](/documentation/Swift/Sequence) --- Copyright © 2026 Apple Inc.
