Swift5 Play aac file AvAudioPlayer - swift

Question

I currently play a wav file with the code below. But now i have compressed the files to aac-files and i can't figure out how to play them? I tried to change the withExtension to "aac" instead but no sound. Any ideas?
guard let url = Bundle.main.url(forResource: fileName, withExtension: "aac") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
let audioPlayer = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.ac3.rawValue)
audioPlayer.volume = currentVolume
newAudioPlayer.audioPlayer.play()
} catch let error {
print(error.localizedDescription)
}

If you need to play AAC files you can use AVAudioEngine audio player node:
import UIKit
import AVFoundation
class ViewController: UIViewController {
let audioEngine = AVAudioEngine()
let player = AVAudioPlayerNode()
override func viewDidLoad() {
super.viewDidLoad()
let url = Bundle.main.url(forResource: "audio_name", withExtension: "aac")!
do {
let audioFile = try AVAudioFile(forReading: url)
guard let buffer = AVAudioPCMBuffer(pcmFormat: audioFile.processingFormat, frameCapacity: .init(audioFile.length)) else { return }
try audioFile.read(into: buffer)
audioEngine.attach(player)
audioEngine.connect(player, to: audioEngine.mainMixerNode, format: buffer.format)
try audioEngine.start()
player.play()
player.scheduleBuffer(buffer, at: nil, options: .loops)
} catch {
print(error)
}
}
}
