## Description

Control motorized camera docks and enable intelligent subject tracking using DockKit. Use when discovering DockKit-compatible accessories, implementing camera subject tracking for faces or bodies, controlling dock motors for pan and tilt, configuring framing behavior, setting regions of interest, or building video apps with automatic camera tracking.

# DockKit

Framework for integrating with motorized camera stands and gimbals that
physically track subjects by rotating the iPhone. DockKit handles motor
control, subject detection, and framing so camera apps get 360-degree pan
and 90-degree tilt tracking with no additional code. Apps can override
system tracking to supply custom observations, control motors directly,
or adjust framing. iOS 17+, Swift 6.3.

## Setup

Import DockKit:

```swift
import DockKit
```

DockKit requires a physical DockKit-compatible accessory and a real device.
The Simulator cannot connect to dock hardware.

DockKit itself requires no special entitlements or DockKit-specific
Info.plist keys. Camera apps that use device cameras still need normal
camera privacy handling, including `NSCameraUsageDescription`. The framework
communicates with paired accessories automatically through the DockKit
system daemon.

The app must use AVFoundation camera APIs. DockKit hooks into the camera
pipeline to analyze frames for system tracking.

## Discovering Accessories

Use `DockAccessoryManager.shared` to observe dock connections:

```swift
import DockKit
