# Adding AR Capabilities

Now that you have successfully integrated the echo3D SDK into Xcode, it's time to add AR capabilities to your project.

[SceneKit](https://developer.apple.com/documentation/scenekit) is an AR rendering engine that allows you to develop native iOS and visioOS apps in Xcode.

## Adding 3D content

Add a **model asset** or **video asset** through the platform. You can choose **any type of target**. Here's how:

{% content-ref url="/pages/-M41wQICYWUWeloxCkls" %}
[Add Assets](/web-console/how-to-add-content.md)
{% endcontent-ref %}

## Setting Up an Application

Replace the `ViewController.swift` file in the project with the one provided as an example in the SDK.

This view controller example will fetch and show all the 3D models added to the platform.

{% hint style="info" %}
You can load models with the `loadAllNodes` method which will load all models or load a single scene by entry ID using the `loadSceneFromEntryID` method.
{% endhint %}

## Launching the iOS App

Run your app on a [compatible iOS device](https://developer.apple.com/library/archive/documentation/DeviceInformation/Reference/iOSDeviceCompatibility/DeviceCompatibilityMatrix/DeviceCompatibilityMatrix.html).

{% hint style="warning" %}
Make sure you have set up signing for your app! This can be found by selecting your project name under files and selecting `Signing & Capabilities`.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.echo3d.com/swift/adding-ar-capabilities.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
