# Download and installation

> Download and set up the Duix iOS SDK demo project to quickly test real-time digital human capabilities.

## Overview

This section provides the setup guide for the **Duix iOS SDK demo project**,
which allows developers to experience the SDK’s real-time digital human capabilities — including initialization, rendering, and audio-video interaction — directly in **Xcode**.

***

## Step 1: Download the iOS Demo

Click below to download the latest official iOS demo package:

👉 [**duix-cloud-demo-ios\_1.2.7.zip**](https://duix-sgp.obs.ap-southeast-3.myhuaweicloud.com/duix/sdk/duix-cloud-demo-ios_1.2.7.zip)

> **Note:**
> The demo project includes all required SDK dependencies and configuration for quick testing.

***

## Step 2: Open the Project in Xcode

1. Extract the downloaded `.zip` file.
2. Open the project folder in **Xcode 14.0 or later**.
3. Wait for Xcode to automatically index and resolve dependencies.
4. Confirm that your **iOS deployment target** matches your connected device or simulator.

***

## Step 3: Configure and Run

1. Select your build target (e.g., iPhone 14 Pro).
2. Click **Run ▶️** to launch the demo.
3. Once initialized, the digital human should appear and respond in real time.

> **Tip:**
> The first run may require microphone and camera permissions. Grant access when prompted.

## Environment Requirements

| Component   | Minimum Version  | Notes                                             |

| **macOS**   | 12.0 (Monterey)  | Required for Xcode 14 or higher                   |
| **Xcode**   | 14.0+            | Enable Developer Mode for device testing          |
| **iOS**     | 15.0+            | Recommended for best SDK performance              |
| **Network** | HTTPS (TLS 1.2+) | WebRTC requires a secure connection to `duix.com` |

## Troubleshooting

* **Build failed?** Ensure **CocoaPods** and **Xcode Command Line Tools** are up to date.
* **Network issues?** Confirm your device can reach `duix.com` and your firewall allows WebRTC ports.
* **Permissions denied?** Re-enable microphone and camera in **Settings → Privacy → App Permissions**.
