# Intertrust ExpressPlay on iOS

This article describes how to configure Intertrust ExpressPlay DRM with THEOplayer.

Head to our page on [DRM](https://docs-preview.optiview.dolby.com/pr-863/theoplayer/how-to-guides/ios/drm/introduction.md) for more general information.

> **Note**
>
> Support for this DRM system has not been verified on the iOS and tvOS SDKs.

## Integration

We provide open-source DRM integrations which are easy to maintain and allow for a modular approach. You can find them in the [DRM integration samples repository](https://github.com/THEOplayer/samples-drm-integration), alongside guides on how to integrate and use them.

There currently is no ready-made integration for this DRM provider: you can choose to develop one based on the examples in the repository, or get in contact with us about making one.

## Code example

**Not verified.**

```swift
// let headers = [["<KEY>": "<VALUE>"]]
let drmConfiguration = FairPlayDRMConfiguration(
    licenseAcquisitionURL: "<LICENSE_KEY_URL_FAIRPLAY>",
    certificateURL: "<CERTIFICATE_URL>"
        // , headers: headers, licenseType: <LICENSE_TYPE>
)
let typedSource = TypedSource(src: "<HLS_STREAM_URL>", type: "application/x-mpegurl", drm: drmConfiguration)
let sourceDescription = SourceDescription(source: typedSource)
theoplayer.source = sourceDescription
```
