Swift 3: AVAudioPlayer not playing sound

I have a struct with my audio player in it: 

struct MT_Audio {

    func playAudio(_ fileName:String, _ fileExtension:String,  _ atVolume:Float) {
        var audioPlayer = AVAudioPlayer()
        if let  audioPath = Bundle.main.path(forResource: fileName, ofType: fileExtension) {
            let audioURL = URL(string:audioPath)
            do {
                audioPlayer = try AVAudioPlayer(contentsOf: audioURL!)
                audioPlayer.volume = atVolume
                audioPlayer.prepareToPlay()
                audioPlayer.play()
            } catch {
                print(error)
            }
        }
    }
}

//I'm calling it in viewDidLoad like this: 

    guard let fileURL = Bundle.main.url(forResource:"heartbeat-01a", withExtension: "mp3") 
         else {
                print("can't find file")
                return
            }

       let myAudioPlayer = MT_Audio() //<--RESOLVED THE ISSUE BY MAKING THIS A PROPERTY OF THE VIEWCONTROLLER
       myAudioPlayer.playAudio("heartbeat-01a", "mp3", 1.0)

Since it doesn't crash and burn on the guard I know the file is there. I've also put a break point in after the try and I am getting to the audio player. When I go to the actual file and click on it in Xcode it plays. This fails on both the sim and device. Any help would be appreciated.

Looks like your audioPlayer is only stored within your playAudio function.

Try to keep the audioPlayer as an variable inside your class like this:

struct MT_Audio {

    var audioPlayer: AVAudioPlayer?

    mutating func playAudio(_ fileName:String, _ fileExtension:String,  _ atVolume:Float) {

        // is now member of your struct -> var audioPlayer = AVAudioPlayer()
        if let  audioPath = Bundle.main.path(forResource: fileName, ofType: fileExtension) {
            let audioURL = URL(string:audioPath)
            do {
                let audioPlayer = try AVAudioPlayer(contentsOf: audioURL!)
                audioPlayer.volume = atVolume
                audioPlayer.prepareToPlay()
                audioPlayer.play()
            } catch {
                print(error)
            }
        }
    }
}
