ARKit: What iOS devices support ARKit?

ARKit is supported on iPhone 6s and later, iPad Pro models, and the latest iPad models. It requires iOS 11 or later. Apple Vision Pro also supports ARKit with enhanced capabilities through visionOS.

Source
ARKit: Can ARKit work offline?

ARKit can function offline for tracking and scene understanding since these operations run locally on the device. However, multiplayer AR features and cloud-based object detection require internet connectivity.

Source
ARKit: Does ARKit integrate with game engines?

Yes, ARKit integrates with Unity through the Unity ARKit Plugin and with Unreal Engine. Developers can also use it with Metal, SceneKit, and Apple's RealityKit framework.

Source
ARKit: What are ARKit's limitations with location-based AR?

ARKit's location-based positioning has accuracy limitations. Image-based positioning is primarily useful in urban areas, and beacon-based navigation provides accuracy of 3-5 meters, which is insufficient for precise AR applications requiring 1-meter accuracy or better.
