I just need to start "AVAudioplayer" after 4 hours of delay. I understand that this is only possible through a "notification", which greatly complicates my development...

I need to turn on "AVAudioPlayer", what if I just turn on the audio in the background without sound so that the application does not block, and after 4 hours I turn on the sound? Is it even possible? Will such an application be missed?

It turns out that there is an option with only notifications? There is no way to ask the user to somehow allow this?
