I have faced same problem in my current project but i have handle like this.

player?.event.playbackEnd.addListener(self, handleAudioPlayerStatePlayBackEnd)
func handleAudioPlayerStatePlayBackEnd(state: AudioPlayer.PlaybackEndEventData) {
            if state == .playedUntilEnd{
      // Reload your audio again and reset UI also            
   }
 }

audioPlayer.togglePlaying()
}

not working still @sukh1993 sir

[sukh1993]

@nishant6042 check with break points, Is your player reload the url or not on play button. if It is not working change stop method to pause.

[nishant6042]

@sukh1993 sir working when doing pause instead of stop but doing that it pauses i want to restart from start when stop clicked

[sukh1993]

@nishant6042 I will working this issue, this is bug on swift Audio side.

[nishant6042]

So whats the alternate for now?

[nishant6042]

and also what should i do to play in background also when i leave the screen @sukh1993 sir

[sukh1993]

Hi @nishant6042
Are you manage cache?
means i load one audio and then play again, it will play from without load.
If you did this please let me know, how can be?
