# contentType

The UTI that specifies the type of data contained by the requested resource.

## Declaration

```swift
var contentType: String? { get set }
```

## Discussion

Discussion Before finishing loading an AVAssetResourceLoadingRequest instance, if its contentInformationRequest property is  not nil, set the value of this property to a UTI indicating the type of data contained by the requested resource. When responding to an AVAssetResourceLoadingRequest for a FairPlay Streaming key, only set contentType to AVStreamingKeyDeliveryContentKeyType, AVStreamingKeyDeliveryPersistentContentKeyType, or nil. The value of contentType must be contained in the allowedContentTypes property or nil.
