AVAudioPlayer is not playing in swift. How to fix it? - swift

Question

In my app I want to integrate a AVAudioPlayer in my app. But I can`t here anything.
Thats my code:
import UIKit
import AVFoundation
class NotenAnsicht: UIViewController{
var PlaybackPlayer:AVAudioPlayer = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
PlaybackAudioAufsetzen()
}
func PlaybackAudioAufsetzen(){
do{
let audioPath = Bundle.main.path(forResource: "song", ofType: "mp3")
try PlaybackPlayer = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL)
print("Song set")
}
catch{
print("there was an Error")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#objc func PlaybayStarten(sender:UIButton){
PlaybackPlayer.play()
PlaybackPlayer.volume = 1
print(PlaybackPlayer.isPlaying)
print("Song should play")
}
}
I have no idea where the problem is. All functions get called properly. And the audioplayer is not defined locally. After PlaybackPlayer.play(), PlaybackPlayer.isPlaying returns true. I just can`t here anything.
Do you have any idea where the problem is?

Answer 1

set try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback) and try AVAudioSession.sharedInstance().setActive(true) in your do block before setting audioPath.
your code should be look like that.
func PlaybackAudioAufsetzen(){
do{
let audioPath = Bundle.main.path(forResource: "song", ofType: "mp3")
/// this code will make this app ready to takeover the device audio
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try AVAudioSession.sharedInstance().setActive(true)
try PlaybackPlayer = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL)
print("Song set")
}
catch let error {
print(error.localizedDescription)
}
}
