# Install the iOS 14 support package

> Install the iOS 14 Support package to enable SKAdNetwork and App Tracking Transparency features in your Unity project. The package includes ad network ID aggregation and a customizable context screen.

If your iOS application is made with Unity, installing the iOS 14 support package provides utilities for Apple's [SKAdNetwork](https://developer.apple.com/documentation/storekit/skadnetwork) and [`AppTrackingTransparency`](https://developer.apple.com/documentation/apptrackingtransparency) frameworks by aggregating proper ad network IDs and providing access to relevant Apple developer APIs. It also provides a convenient and customizable context screen, which you can use to encourage users to opt-in to ad tracking on their iOS device.

There are two ways to install the Unity iOS 14 Support package, depending on the version of Unity you use.

If you use Unity version 2018.1 or greater, follow these steps:

1. In the Unity Editor, select **Window** > **Package Manager** to open the Package Manager window.
2. In the Package Manager window, select the **iOS 14 Advertising Support** package, then select **Install**.

If you use any other version of Unity, follow these steps:

1. Download the [iOS 14 Support package](https://github.com/Unity-Technologies/com.unity.ads.ios-support) repository to your hard drive.
2. In the Unity Editor, select **Window** > **Package Manager** to open the Package Manager window.
3. Select the **+** button, then **Add package from disk...**.
4. Navigate to your local copy of the package repo and select the package JSON (`..\com.unity.ads.ios-support-master\com.unity.ads.ios-support\package.json`), then select **Open** to install the package.

If successful, the iOS 14 Support package will appear in the Package Manager list. For more information, refer to [installing packages](https://docs.unity3d.com/2019.4/Documentation/Manual/PackagesList.html).

| `SkAdNetworkUpdateConversionValue(int conversionValue)`                              | Use this method to [update the attribution conversion value](https://developer.apple.com/documentation/storekit/skadnetwork/3566697-updateconversionvalue?language=objc).                                     |
| `SkAdNetworkRegisterAppForNetworkAttribution()`                                      | Use this method to [register for attribution](https://developer.apple.com/documentation/storekit/skadnetwork/2943654-registerappforadnetworkattributi?language=objc).                                         |
| `RequestAuthorizationTracking(RequestAuthorizationTrackingCompleteHandler callback)` | Use this method to [request the user permission request](https://developer.apple.com/documentation/apptrackingtransparency/attrackingmanager/3547037-requesttrackingauthorization).                           |
| `AuthorizationTrackingStatus GetAuthorizationTrackingStatus()`                       | Use this method to check the app tracking transparency (ATT) [authorization status](https://developer.apple.com/documentation/apptrackingtransparency/attrackingmanager/3547038-trackingauthorizationstatus). |

## Generating a properties list file

The [information property list](https://developer.apple.com/documentation/bundleresources/information_property_list) (`Info.plist`) file is a resource that contains key-value pairs to identify and configure iOS apps. You will need it to implement ad network ID and ATT requirements. When you [build](https://docs.unity3d.com/Manual/BuildSettings.html) your Unity project to iOS with the Advertising and iOS 14 Advertising Support packages installed, the process generates a plist file in the build's root directory.

**Next steps**: Refer to the documentation on how to [configure ad network IDs](/monetization/privacy/ios14/configure-ad-network-ids.md).
