Integrate iOS device camera and motion features to produce augmented reality experiences in your app or game.


Augmented reality (AR) describes user experiences that add 2D or 3D elements to the live view from a device's camera in a way that makes those elements appear to inhabit the real world. ARKit combines device motion tracking, camera scene capture, advanced scene processing, and display conveniences to simplify the task of building an AR experience.


First Steps

About Augmented Reality and ARKit

Discover supporting concepts, features, and best practices for building great AR experiences.


A shared object that manages the device camera and motion processing needed for augmented reality experiences.


The abstract base class for AR session configurations.

World-Based AR Experiences

Building Your First AR Experience

Create an app that runs an AR session and uses plane detection to place 3D content using SceneKit.

Handling 3D Interaction and UI Controls in Augmented Reality

Follow best practices for visual feedback, gesture interactions, and realistic rendering in AR experiences.


A configuration that uses the rear-facing camera, tracks a device's orientation and position, and detects real-world flat surfaces.


A configuration that uses the rear-facing camera and tracks only a device's orientation.


Information about the position and orientation of a real-world flat surface detected in a world-tracking AR session.

Face-Based AR Experiences

Creating Face-Based AR Experiences

Place and animate 3D content that follows the user’s face and matches facial expressions, using the TrueDepth camera on iPhone X.


A configuration that tracks the movement and expressions of the user’s face using the TrueDepth camera.


Information about the pose, topology, and expression of a face detected in a face-tracking AR session.

Standard Views


A view for displaying AR experiences that augment the camera view with 3D SceneKit content.


A view for displaying AR experiences that augment the camera view with 2D SpriteKit content.

Custom Views

Displaying an AR Experience with Metal

Build a custom AR view by rendering camera images and using position-tracking information to display overlay content.

Real-World Objects and Positions


Information about a real-world surface found by examining a point in the device camera view of an AR session.


A real-world position and orientation that can be used for placing objects in an AR scene.


A real-world object in a scene for which ARKit tracks changes to position and orientation.

Camera and Scene Details


A video image and position tracking information captured as part of an AR session.


Information about the camera position and imaging characteristics for a captured video frame in an AR session.


Estimated scene lighting information associated with a captured video frame in an AR session.


Estimated environmental lighting information associated with a captured video frame in a face-tracking AR session.
