回答1:

I noticed when trying to update now playing info dictionary you have to fill key with data even empty string.

are you sure trackName, albumName, artistName are not nil ?

ModernAVPlayer has a good example: check this "NowPlaying" code

Thanks all, I found the solution, my last code in set category

self.audioSession.setCategory(AVAudioSession.Category.playback , mode: .default , options: .mixWithOthers )

and the solution is

self.audioSession.setCategory(AVAudioSession.Category.playback , mode: .default , options: .init(rawValue: 0) )
