Swift 3 - 將包含內容的文件夾從主包復制到文檔目錄

Question

我的主要包中包含文件夾，我想在首次啟動應用程序時將它們復制/剪切到文檔目錄，以便從那里訪問它們。 我見過一些例子，但是他們都在Obj-C中，我正在使用Swift 3.我怎么能這樣做？

我設法使用2個功能：

func copyFolders() {
    let filemgr = FileManager.default
    filemgr.delegate = self
    let dirPaths = filemgr.urls(for: .documentDirectory, in: .userDomainMask)
    let docsURL = dirPaths[0]

    let folderPath = Bundle.main.resourceURL!.appendingPathComponent("Test").path
    let docsFolder = docsURL.appendingPathComponent("Test").path
    copyFiles(pathFromBundle: folderPath, pathDestDocs: docsFolder)
}

func copyFiles(pathFromBundle : String, pathDestDocs: String) {
    let fileManagerIs = FileManager.default
    fileManagerIs.delegate = self

    do {
        let filelist = try fileManagerIs.contentsOfDirectory(atPath: pathFromBundle)
        try? fileManagerIs.copyItem(atPath: pathFromBundle, toPath: pathDestDocs)

        for filename in filelist {
            try? fileManagerIs.copyItem(atPath: "\(pathFromBundle)/\(filename)", toPath: "\(pathDestDocs)/\(filename)")
        }
    } catch {
        print("\nError\n")
    }
}
