Note that you must call AVAudioSession.sharedInstance().setCategory() with the mode parameter in Swift 4.2.

import AVFoundation

var audioPlayer: AVAudioPlayer?

func playSound() {
    if let audioPlayer = audioPlayer, audioPlayer.isPlaying { audioPlayer.stop() }

    guard let soundURL = Bundle.main.url(forResource: "audio_file", withExtension: "wav") else { return }

    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: AVAudioSession.Mode.default)
        try AVAudioSession.sharedInstance().setActive(true)
        audioPlayer = try AVAudioPlayer(contentsOf: soundURL)
        audioPlayer?.play()
    } catch let error {
        Print.detailed(error.localizedDescription)
    }
}
