错误代码

let originalURL = Bundle.main.url(forResource: "12345", withExtension: "aac")
var audioFile : AudioFileID? = nil
let osStatus =
          AudioFileOpenURL(originalURL as CFURL, .readPermission,0, &audioFile)
      
      if osStatus != noErr {
          print("加载失败")
      }

报错信息 OSStatus 返回:2003334207
原因：readPermission 权限使用错误

正确的代码

let originalURL = Bundle.main.url(forResource: "12345", withExtension: "aac")
var audioFile : AudioFileID? = nil
let osStatus =
          AudioFileOpenURL(originalURL as CFURL, .readPermission,0, &audioFile)
      
      if osStatus != noErr {
          print("加载失败")
      }
