Answer 1

您可以使用以下代码：

let audioUrlStr = "https://firebasestorage.googleapis.com/v0/b/sweetwalk-192506.appspot.com/o/Heritage%20Point1%2FAudios%2Fsmstreet1.mp3?alt=media&token=a3224b55-6039-4c6f-ac4e-78b9cf818c89"
if let url = URL(string: audioUrlStr) {
   do {
      try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayAndRecord)
      self.audioPlayer = try AVAudioPlayer(data: Data(contentsOf: url))
      self.audioPlayer!.delegate = self
      self.audioPlayer!.volume = 2.0
      self.audioPlayer!.prepareToPlay()
      print("Audio ready to play")
      self.audioPlayer!.play()
   } catch let error {
        print("error occured while audio downloading")
        print(error.localizedDescription)
   }
}
