How to lower the volume of music in swift?

Question

I am creating a SpriteKit Game with background music looping. The problem is that the music is too loud. How do I lower the volume?

Here is the code I used to set up the music

    var backGroundMusic = AVAudioPlayer()
    var bgMusicUrl:NSURL = NSBundle.mainBundle().URLForResource("BackGround", withExtension: "wav")
    backGroundMusic = AVAudioPlayer(contentsOfURL:bgMusicUrl, error: nil)
    backGroundMusic.numberOfLoops = (-1)
    backGroundMusic.prepareToPlay()
    backGroundMusic.play()

Have you tried this?

backGroundMusic.volume = 0.5

Volume goes from 0.0 to 1.0 (full volume). https://developer.apple.com/library/prerelease/ios/documentation/AVFoundation/Reference/AVAudioPlayerClassReference/index.html

I have the same issue. I tried this, but whatever I do, its always on max volume. Even with the value 0.1. Not sure what to do :s – Mr.Boon Feb 24 '15 at 09:16
@Mr.Boon seems I don't have this problem. – Saorikido Nov 04 '15 at 10:15

@Mr.Boon make sure you set the volume after play() – user323774 May 01 '16 at 15:15

Try this:

backGroundMusic.setVolume(0.05, fadeDuration: TimeInterval(1))
