xcode - AVPlayer not working iOS Swift -

i'm trying play external html video avplayer reason can't work. i've been trying read every question none of suggested answers seems work. i've tried find if has been changed swift 3 or xcode 8.0 no luck.

is code wrong or need else make work? enable in capabilities or similar?

    let url = nsurl(fileurlwithpath: "http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")     let player = avplayer(url: url url)     let playerviewcontroller = avplayerviewcontroller()     playerviewcontroller.player = player      playerviewcontroller.view.frame = cgrect(x: 0, y: 0, width: 100, height: 200)     self.view.addsubview(playerviewcontroller.view)     self.addchildviewcontroller(playerviewcontroller)      player.play() 

try: let url = nsurl(string:"your_url")

string: produces nsurl represents string given. string "http://www.google.com" , url represents http://www.google.com.

fileurlwithpath: takes path, not url, , produces nsurl represents path using file:// url. if give /foo/bar/baz url represent file:///foo/bar/baz.
