我在我的应用程序中集成了自动完成事件。配置textfield时出现此错误

  

不能使用索引为“ NSAttributedStringKey”的下标“ [String:AnyObject]”的值

请检查以下代码:

fileprivate func configureTextField(){
    print("i am here 4")
    autocompleteTextfield.autoCompleteTextColor = UIColor(red: 128.0/255.0, green: 128.0/255.0, blue: 128.0/255.0, alpha: 1.0)
    autocompleteTextfield.autoCompleteTextFont = UIFont(name: "HelveticaNeue-Light", size: 12.0)!
    autocompleteTextfield.autoCompleteCellHeight = 35.0
    autocompleteTextfield.maximumAutoCompleteCount = 20
    autocompleteTextfield.hidesWhenSelected = true
    autocompleteTextfield.hidesWhenEmpty = true
    autocompleteTextfield.enableAttributedText = true
    ***var attributes = [String:AnyObject]()
    attributes[NSForegroundColorAttributeName] = UIColor.black
    attributes[NSFontAttributeName] = UIFont(name: "HelveticaNeue-Bold", size: 12.0)
    autocompleteTextfield.autoCompleteAttributes = attributes***           
}

我在 NSForegroundColorAttributeName,NSFontAttributeName和属性上出错     对于自动完成功能,我导入了自动完成UITextfield文件。我在以下方法中遇到了以上错误:

> open var autoCompleteAttributes:[String:AnyObject]?
  fileprivate func commonInit(){
      hidesWhenEmpty = true
      autoCompleteAttributes = [NSForegroundColorAttributeName.rawValue:UIColor.black]
      autoCompleteAttributes![NSFontAttributeName] = UIFont.boldSystemFont(ofSize: 12)
      self.clearButtonMode = .always
      self.addTarget(self, action: #selector(AutoCompleteTextField.textFieldDidChange), for: .editingChanged)
      self.addTarget(self, action: #selector(AutoCompleteTextField.textFieldDidEndEditing), for: .editingDidEnd)
  }

此行出现错误 autoCompleteAttributes![NSFontAttributeName] 。我没有发生任何事情,请检查代码...
