Can anyone help me with the following output which is related to playing sounds/music in a SpriteKit game I'm working on? [plugin] AddInstanceForFactory: No factory registered for id <CFUUID 0x60000276b020> F8BB1C28-BAE8-11D6-9C31-00039315CD46 I'm new to SpriteKit and I've searched the web for answers and found quite a few post concerning the warning (I wouldn't call it an error because the game and sound/music output works perfectly), but no definitive answers on fixing it. I get the warning regardless of how I play the music, adding SKAudioNode to the scene, creating an AVAudioPlayer, etcetera. I suppose I could just ignore the warning as it doesn't seem to impact my game, but I just hate not understanding warnings in the Xcode output window. I'm also getting the below in the output window which I believe is related. AudioObjectGetPropertyData: no object with given ID 0 throwing -10878
