使用Xcode 8+并创建新的空白项目时,运行应用程序时会显示以下日志:

有人知道为什么吗？是因为我正在为 WatchOS 开发吗？
负责播放声音的经理：
import Foundation
import AVFoundation
final class SoundManager {
var player: AVAudioPlayer?
func playSound(name: String, volume: Float = 1.0) {
if let url = Bundle.main.url(forResource: name, withExtension: "aif") {
do {
player = try AVAudioPlayer(contentsOf: url)
player?.prepareToPlay()
player?.setVolume(volume, fadeDuration: 0.5)
} catch {
print("Error getting the audio file: \(error.localizedDescription)")
}
}
player?.play()
}
}
