How to play the encryted videos in fairplay SDK?

I'm trying to play the encrypted video from the fairplay sdk.


I tryed both the assetRessouceLoader and ContentKeySession method, but I'm unable to play the encypted video from the SDK. I am using the key and the initialization vector from the Key.txt file.


I dont know how to do with the AssetRessourceLader because of the line

resourceLoadingRequest.dataRequest?.respond(with: ckcData)

but I dont know what to put into ckcData.


For the ContentKeySessionResponse I use this init(clearKeyData: Data, initializationVector: Data?).


Is this the right Path?


I'm trying this in swift and in c# with Xamarin.


Thanks in advance!!
