Cannot find type 'NSSound' in scope-CodePudding

In this tutorial: https://swiftui-lab.com/swiftui-animations-part4/

I'm trying to run the metronome, about 1/2 way down the page. It's a simple call to NSSound and I get an error cannot find the type. I change that type to "Any" and then it doesn't find NSSound. I think it should be apart of UIKit, but it doesn't seem to be working.

Q. How can I run NSSound() in an iOS, SwiftUI app?

Other imports don't resolve the error:

import UIKit
import AudioUnit
import AVFAudio
import AVFoundation
import AVKit
import AudioUnit
import CoreAudio
import Foundation



let bellSound: NSSound? = {
    guard let url = Bundle.main.url(forResource: "bell", withExtension: "mp3") else { return nil }
    return NSSound(contentsOf: url, byReference: true)
}()

NSSound is only available in macOS environment(actually macOS 10 . Not in iOS environment. Check the documentation here for further details.
