是否需要 AudioServicesDisposeSystemSoundID？

import AudioToolbox

class SoundPlayer {
    var soundID: SystemSoundID = 0

    init?(url: URL) {
        let soundURL = url as CFURL
        let error = AudioServicesCreateSystemSoundID(soundURL, &soundID)
        if error != kAudioServicesNoError {
            return nil
        }
    }

    deinit {
        AudioServicesDisposeSystemSoundID(soundID)
    }

    func play() {
        AudioServicesPlaySystemSound(soundID)
    }
}
