MPVolumeView has a slider, and by changing the value of the slider, you can change the device volume. I wrote an MPVolumeView extension to easily access the slider:

extension MPVolumeView {
    var volumeSlider:UISlider {
        self.showsRouteButton = false
        self.showsVolumeSlider = false
        self.hidden = true
        var slider = UISlider()
        for subview in self.subviews {
            if subview.isKindOfClass(UISlider){
                slider = subview as! UISlider
                slider.continuous = false
                (subview as! UISlider).value = AVAudioSession.sharedInstance().outputVolume
                return slider
        return slider
