Audio not playing in SwiftUI - swift

Question

I'm having an issue getting an audio file to play when the function is called.
I am using an AVAudioPlayer to try and play the file following the instructions form here:
https://www.hackingwithswift.com/example-code/media/how-to-play-sounds-using-avaudioplayer
After the button is pressed in the view, it calls a func to play the sound, but from what I can tell, nothing is played. There are no errors thrown, and the file is found. The app also uses a speech synthesizer when a button is pushed, and that plays fine.
I looked around stack overflow and followed the instructions from here:
Where to place code for audio playback in a SwiftUI app
But still the audio is not played when the button is pushed.
Here is the func:
func playSound() {
var sound = AVAudioPlayer()
if let path = Bundle.main.path(forResource: "TryAgain", ofType: "wav") {
do {
sound = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
print("Playing sound")
sound.play()
} catch {
print( "Could not find file")
}
}
Here is the class:
class Player: BindableObject {
let willChange = PassthroughSubject<Player, Never>()
var isPlaying: Bool = false {
willSet {
willChange.send(self)
}
}
func playSound() {
var sound = AVAudioPlayer()
if let path = Bundle.main.path(forResource: "TryAgainWav", ofType: "wav") {
do {
sound = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
print("Playing sound")
sound.play()
} catch {
print( "Could not find file")
}
}
}
}
Update: Not sure if this helps, but I built this in with IB instead of SwiftUI and noticed the same message is printed in the console when I click the button to play the audio file:
2019-07-22 11:29:41.075568-0700 PlaySoundPrac[13952:46549155] [plugin] AddInstanceForFactory: No factory registered for id F8BB1C28-BAE8-11D6-9C31-00039315CD46
Any help would be greatly appreciated

I'm pretty new myself, but I'll do my best. What happens if you move the declaration of AVAudioPlayer outside the function? For example:
import Combine
class Player: ObservableObject {
var sound: AVAudioPlayer!
let willChange = PassthroughSubject<Player, Never>()
var isPlaying: Bool = false {
willSet {
willChange.send(self)
}
}
func playSound() {
if let path = Bundle.main.path(forResource: "TryAgainWav", ofType: "wav") {
do {
sound = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
print("Playing sound")
sound.play()
} catch {
print( "Could not find file")
}
}
}
}
Try this out and let me know if it works or not! Thanks.

I had a problem that audio was not played on iOS 13 Simulator in Xcode 11.5 while it was okay in Xcode SwiftUI preview and physical device.
