To control the volume, just drag a view in Interface Builder (not View Controller, just View) then at the custom class type MPVolumeView. When you run the app on a real device (in simulator it does not show), you will be able to control the volume.

@Kristoff, did it work? If it did not, try to connect an IBOutlet of the MPVolumeView and reply. – Toma Feb 05 '17 at 18:57

@Kristoff, just drag a view in the view controller, and at the custom class of the view type MPVolumeView. Then, create a new Swift file and a view controller class, assign it to the view controller and create an IBOutlet here. There is no screenshot as it is not visible in storyboard or simulator, just on a real device. – Toma Feb 06 '17 at 07:25

Oh yes, it showed but I can not swipe it. what I want to do is I can use phone control and user can swipe control also (both). Thanks – Kristoff Feb 07 '17 at 02:04

What do you mean by "I can not swipe it" ? And could you, please, explain better what you want to do? – Toma Feb 08 '17 at 18:26
