previous button

But you can fix the button back so that it does not wind the audio up to 0 second, and immediately switches to the previous track, if there is one

@rastaman111 Thank you for your suggestion.

Do you mean that your change request helps #12 fixed?
I think that in absolute terms, the current behavior makes sense because some popular music apps like Apple Music and Amazon Music follow the same.

That said, it would be appropriate to add the new option like always_previous_track that is set to false as default. Does it work for you?

[rastaman111]

I think this will not change problem #12, but it will help to solve other problems, such as the application crash, but it will also add convenience

@yoheimuta Hey. so there is some news about the back button, so that you can wind not for 0 second, but immediately to the previous track, you can implement as two functions to choose from

@rastaman111 Thank you for your confirmation.
Can you make a PR whenever you have time? Otherwise, it falls under I will get to it when I have time.

  	private func playPrevious() -> Observable<()> {
  	if 1 < (player?.currentTime().seconds ?? 0) {
  	return seek(toSecond: 0)
  	.flatMapLatest { [weak self] _ -> Driver<CMTime?> in
  	guard let weakSelf = self else { return .just(nil) }
  	return weakSelf.rx.currentItemTime()
  	}
  	.asObservable()
  	.filter { ($0?.seconds ?? 0) <= 1 }
  	.map { [weak self] _ in
  	self?.forceUpdateNowPlayingInfo.accept(())
  	}
  	.take(1)
  	}
  	return play(atIndex: playIndex - 1)
  	}

  is a related part. Maybe if 1 < (player?.currentTime().seconds ?? 0) && !always_previous_track { would be a main change.
