Question

我想知道：用户点击按钮＆gt;取景器窗口将打开＆gt;用户选择一个或多个文件＆gt;并且此选定的文件/文件应复制到文档文件夹中。

我现在所拥有的：

@IBAction func copyFile(_ sender: Any) {
   let dialog = NSOpenPanel();
   dialog.showsHiddenFiles = false
   dialog.canChooseDirectories = false
   dialog.canCreateDirectories = false
   dialog.allowsMultipleSelection = true
   dialog.allowedFileTypes = ["pdf","doc","docx"]

   if (dialog.runModal() == NSModalResponseOK) {
       for x in 0..<dialog.urls.count {

          // documents folder path
          let dictDocuments = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0])

          // folder name
          let logsPath = dictDocuments.appendingPathComponent("Files/")

          print("SOURCE: ",dialog.urls[x].absoluteURL)
          print("TARGET: ",logsPath!)

          do {
              try FileManager.default.copyItem(at:    dialog.urls[x].absoluteURL, to: logsPath!)
          } catch let error as NSError {}
       }
    } else {
        return
    }
}

这是输出：

SOURCE:  file:///Users/XXX/Downloads/test.pdf
TARGET:  file:///Users/XXX/Documents/Files/
open on /Users/XXX/Documents/Files: File exists

文件夹＆＃34; Files＆＃34;存在，但它是空的。我错了什么？

将所选文件复制到文件夹swift3，osx中
