Swift - 同时播放音频文件和Itunes Music

Question

I am currently building a game with swift and spritekit. I want to play a sound in a certain part of the code. Currently I am using AVAudioPlayer. I am currently using this method.

player = try AVAudioPlayer(contentsOfURL: url)
player.prepareToPlay()
player.play()

The sound plays correctly, but if I were to be listening to music through itunes while the sound is played my itunes music is stopped and the sound is played. I have played other people's games in the past where ingame sound effects play and do not effect music that was already playing from another app. Can somone explain how this is achieved.Thanks a bunch.

You'll need to set your audio session to use a category that allows mixing. By default it uses AVAudioSessionCategorySoloAmbient which is non mixable.

I don't know which category will fit your needs but AVAudioSessionCategoryAmbient allows mixing.

AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryAmbient)
