AVPlayer загружает видео иногда, а не загружает другое время

Question

Я использую HCVimeoVideoExtractor. Иногда видео не загружаются. Почему видео загружается иногда, а не загружается в другое время. Я не понимаю, как это иногда может быть хорошо, а иногда нет.

    //Getting url info for video by using exractor
func geturl() {
    if let url = URL(string: calledVideo!) {
        HCVimeoVideoExtractor.fetchVideoURLFrom(url: url, completion: { ( video:HCVimeoVideo?, error:Error?) -> Void in

            if let err = error {
                DispatchQueue.main.async() {
                    let alert = UIAlertController(title: "Error", message: err.localizedDescription, preferredStyle: .alert)
                    alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
                    self.present(alert, animated: true, completion: nil)
                }
                return
            }

            guard let vid = video else {
                print("Invalid video object")
                return
            }

            //play video
            //let player = AVPlayer(url: vid.videoURL[.Quality720p]!)
            let player = AVPlayer(url: vid.videoURL[.Quality360p]!)
            self.playerController.player = player
            self.present(self.playerController, animated: true) {
                player.play()
            }
        })

    }
}

Probably at least one of the constraints in the following list is one you don't want. 
Try this: 
    (1) look at each constraint and try to figure out which you don't expect; 
    (2) find the code that added the unwanted constraint or constraints and     fix it.
