如何使用本地目录中AVPlayerItem类型的元素填充数组

import AVFoundation

func fillArrayWithAVPlayerItemsFromLocalDirectory() -> [AVPlayerItem] {
    var playerItems: [AVPlayerItem] = []
    
    // 本地目录中音视频文件的路径
    let directoryPath = "/path/to/local/directory"
    
    do {
        // 获取本地目录中的文件列表
        let fileURLs = try FileManager.default.contentsOfDirectory(at: URL(fileURLWithPath: directoryPath), includingPropertiesForKeys: nil, options: [])
        
        // 遍历文件列表
        for fileURL in fileURLs {
            // 创建AVPlayerItem对象
            let playerItem = AVPlayerItem(url: fileURL)
            
            // 将AVPlayerItem对象添加到数组中
            playerItems.append(playerItem)
        }
    } catch {
        print("Error: \(error)")
    }
    
    return playerItems
}
