AVAudioPlayer does not think it is playing when it is - swift

Question

I call the superPlay function to start audio playback a little while later I call the superPlay function again to stop the playback. This does not work though because player.isPlaying is false even knowing the sound is clearly playing in an infinite loop. I have no idea why please help!
func superPlay(timeInterval: TimeInterval, soundName: String) {
do {
alarmSound = soundName
//set up audio session
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, options: [.defaultToSpeaker, .duckOthers])
try AVAudioSession.sharedInstance().setActive(true)
let url = Bundle.main.url(forResource: alarmSound, withExtension: "mp3")
player = try! AVAudioPlayer(contentsOf: url!)
player.numberOfLoops = -1
//Start AVAudioPlayer
print(timeInterval)
print(time)
let playbackDelay = timeInterval // must be ≥ 0
if player.isPlaying {
player.stop()
} else {
player.play(atTime: player.deviceCurrentTime + playbackDelay) //time is a TimeInterval after which the audio will start
}
}
catch {
print(error)
}
}
I have spent a couple more days debugging this now. What is happening is the original play is being assigned to a specific AudioPlayer ID for example the print is: "Optional(<AVAudioPlayer: 0x600002802280>)"
When I call the function again to stop the play the AVAudioPlayer is assigned a different ID therefore it does not find that the old player is still playing and moves forward with playing a new sound on top of the old sound.
I am not sure how to store the AVAudioPlayer ID and then call the function so that it checks the store Player for if it is ".isPlaying"??

Answer 1

This happen because you initialize it before stopping current audio. Try this way:-
func superPlay(timeInterval: TimeInterval, soundName: String) {
// If audio is playing already then stop it.
if let audioPlayer = player {
if player.isplaying {
player.stop()
}
}
// Initilize audio player object with new sound
do {
alarmSound = soundName
//set up audio session
try AVAudioSession.sharedInstance().setCategory(.playAndRecord, options: [.defaultToSpeaker, .duckOthers])
try AVAudioSession.sharedInstance().setActive(true)
let url = Bundle.main.url(forResource: alarmSound, withExtension: "mp3")
player = try! AVAudioPlayer(contentsOf: url!)
player.numberOfLoops = -1
//Start AVAudioPlayer
print(timeInterval)
print(time)
let playbackDelay = timeInterval // must be ≥ 0
player.play(atTime: player.deviceCurrentTime + playbackDelay) //time is a TimeInterval after which the audio will start
}
catch {
print(error)
}
}
