iOS SDK

The iOS SDK is a Swift package in the Trinet-SDK repository for capturing video and motion data from a Trinet camera connected to an iPhone over USB.

Minimum iOS	17.0
Language	Swift 5.9, no external dependencies
Cameras	Trinet Mono in iPhone mode
Version	0.2.1

iPhones don't let apps use external USB webcams, so the camera connects in iPhone mode: it appears as a USB network adapter and serves its stream over that link. Put the camera in this mode with a mode file (mode=ncm) or the app's Boot mode setting; the light turns cyan. See USB transports.

Install

Package.swift

dependencies: [
    .package(url: "https://github.com/Panoculon-Labs/Trinet-SDK", from: "0.2.1"),
],
targets: [
    .target(name: "MyApp", dependencies: [
        .product(name: "TrinetSDK", package: "Trinet-SDK"),
    ]),
]

In Xcode: File → Add Package Dependencies…, enter the repository URL and add the TrinetSDK product.

Quick start

import TrinetSDK

let discovery = TrinetDiscovery()
guard let device = await discovery.scan(timeout: 2.0).first else { return }

try await device.connect()
let session = await device.liveSession()
await session.start()

// Live preview in SwiftUI:  LivePreviewView(stream: session.sampleStream)

Task {
    for await batch in session.imuStream {
        // batch.samples: [ImuSample]
    }
}

let handle = try await session.startRecording(in: outputDirectory)   // .mp4 + .imu + .vts
// …
session.stopRecording()
await session.stop()
await device.disconnect()

SwiftUI helpers include a live preview, motion plots, an orientation cube and a playback motion track; MadgwickAHRS computes orientation.

Demo app

The repository includes TrinetApp, a complete SwiftUI demo — device list, live preview with motion plots, recording and playback. To run it you need a Mac with Xcode 16+, an Apple ID and XcodeGen; the iOS guide walks through clone → Xcode → iPhone.
