This is the Youtube's view style. It's a try to mimic Youtube's volume HUD when watching videos on landscape on iDevices. This view style will hide your status bar every time you present it, to give you a cleaner look. If you present it inside a full screen app (without a status bar) it will be presented on the top of a dark background to ensure a better experience. On iPhone X Youtube's style is under the name YoutubeX and it changes it's width for an excellent presentation. You may change the volume level with your finger by touchig the volume line and swipping. Welcome to the Youtube's experience!
