func gettinSongName(){

    let folderUrl = URL(fileURLWithPath: Bundle.main.resourcePath!)

    do {
        let songPath = try FileManager.default.contentsOfDirectory(at: folderUrl, includingPropertiesForKeys: nil, options: .skipsHiddenFiles)
        for song in songPath{
            let mySong = song.absoluteString
            if mySong.contains("mp3") {
                print(mySong)
            }
        }
    } catch  {

    }
}

编写此代码时没有得到任何结果

但是当我输入时我会得到结果.contains("a") 

 func gettinSongName(){

    let folderUrl = URL(fileURLWithPath: Bundle.main.resourcePath!)

    do {
        let songPath = try FileManager.default.contentsOfDirectory(at: folderUrl, includingPropertiesForKeys: nil, options: .skipsHiddenFiles)
        for song in songPath{
            let mySong = song.absoluteString
            if mySong.contains("a") {
                print(mySong)
            }
        }
    } catch  {

    }
}

结果：

Bundle获取特定扩展的所有资源的专用 API是

func gettinSongName() { 
    if let mp3Urls = Bundle.main.urls(forResourcesWithExtension "mp3", subdirectory: nil) {
        for song in mp3Urls {
            print(song)
        }
    }
}
