Integrating Aura iOS Core Haptics SDK with AVPlayer and Custom Shaders

Adding haptic trailers or interactive video cuts into your native iOS application requires synchronizing Apple's `AVPlayer` clock with a low-overhead `CHHapticEngine` instance. The Aura iOS SDK makes this a single-line configuration.

Installing the Swift Package

Add the Aura SDK via Swift Package Manager (SPM):

Initializing the Haptic Video Player

Bind your video URL and `.ahap` bundle together using `AuraPlayerController`:

Handling Audio Session Interruptions

When a phone call arrives or the app moves to background, `CHHapticEngine` will automatically pause and recreate its audio server connection on foreground reactivation, preventing audio crackle or lost tactile sync.

Custom Metal Visualizer Binding

You can subscribe to `hapticPlayer.onHapticParameterUpdate` to drive GPU shader effects (such as screen shake or chromatic aberration) perfectly synchronized with the tactile impact.
