I know it works in Xcode however, I want to create it specifically in the "Answers" template on Swift Playgrounds. Will the code still work on the template or does attaching an audio player and file only work on a new, blank Playground?

Same here,

I have this code which I found on the internet, but it doesn't seem to work on the Playgrounds

 import AVFoundation
import PlaygroundSupport
URLCache.shared = URLCache(memoryCapacity: 0, diskCapacity: 0, diskPath: nil)
let width = 568
let height = 320
let container = UIView(frame: CGRect(x: 0, y: 0, width: width, height: height))
PlaygroundPage.current.liveView = container
PlaygroundPage.current.needsIndefiniteExecution = true
func playVideo(_ url: URL){
    let f=CGRect(x: 0, y: 0, width: width, height: height)
    let playerItem = AVPlayerItem(url: url)
   
    let player=AVPlayer(playerItem: playerItem)
    let playerLayer=AVPlayerLayer(player: player)
   
    playerLayer.frame=f
    container.layer.addSublayer(playerLayer)
    PlaygroundPage.current.liveView = container
   
    player.play()
}
playVideo(URL(string:"http://s3.amazonaws.com/vids4project/sample.mp4")!)

See my answer here. I have both a SwiftUI and UIKit solution.

	import AVFoundation
	import PlaygroundSupport
	URLCache.shared = URLCache(memoryCapacity: 0, diskCapacity: 0, diskPath: nil)
	let width = 568
	let height = 320
	let container = UIView(frame: CGRect(x: 0, y: 0, width: width, height: height))
	PlaygroundPage.current.liveView = container
	PlaygroundPage.current.needsIndefiniteExecution = true
	func playVideo(_ url: URL){
	let f=CGRect(x: 0, y: 0, width: width, height: height)
	let playerItem = AVPlayerItem(url: url)

	let player=AVPlayer(playerItem: playerItem)
	let playerLayer=AVPlayerLayer(player: player)

	playerLayer.frame=f
	container.layer.addSublayer(playerLayer)
	PlaygroundPage.current.liveView = container

	player.play()
	}
	playVideo(URL(string:"http://s3.amazonaws.com/vids4project/sample.mp4")!)
