Declaration
var contentType: String? { get set }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.
