The URL of the media file you want to play. The URL must specify a file; streamed media is not supported. The file may contain audio, video, or both.

If you specify a URL for a file on a remote server, this method downloads the file first and displays a progress indicator showing the progress of the operation. Because WatchKit uses App Transport Security (ATS) when downloading files from a web server, the file must be on a secure server, and the URL must use the https scheme. If your server does not support ATS–level security, download the file yourself before playing it.

Use sharedcontainer, watch extensions, for storing the file.

Any audio you play using this method is routed to a paired Bluetooth audio device if one is available. If no Bluetooth audio device is available, audio is routed to to the Apple Watch speaker.
