How to mute my app programmatically (disable sounds)

Question

I'm creating an app-browser that hides advertising. Almost done. Sometimes there are autoplaying sounds in browser(probably powered with JavaScript)

Now I need to turn off all sounds in this app. I've tried two ways: through AVFoundation and through WebKit.

Please help me to get idea how I can do this. One more variants are were welcome :)

This can be done through the MediaPlayer module:

(MPVolumeView().subviews.filter{ NSStringFromClass($0.classForCoder) == "MPVolumeSlider" }.first as? UISlider)?.setValue(0, animated: false)

Note the two values you can change:

value: how much volume you want (0 in this case)
animated: allowing you to animate the change visually
