Question

我正在尝试制作一个使用firebase进行身份验证和数据库的应用。这是我的第一个使用firebase的应用程序，我无法将文件保存到firebase数据库。我在运行应用程序时没有在控制台中收到任何错误，但它没有保存任何内容到firebase。我阅读了firebase文档并按照说明操作，但我无法使其工作。帮助将不胜感激。这是我的代码导入UIKit 导入Firebase 导入FirebaseDatabase

class AddVC: UIViewController {

 var refAttractions: DatabaseReference! //defining firebase database reference

@IBOutlet weak var addedlbl: UILabel!
@IBOutlet weak var descriptioninfo: UITextField!
@IBOutlet weak var categoryinfo: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()

        // accessing nodes of refAttractiions
     refAttractions = Database.database().reference().child("Attractions")

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func submitbtn(_ sender: Any) {
    addAttractions()
}
func addAttractions(){
    let key = refAttractions.childByAutoId().key //creating id for the  attraction. 
    let attraction = ["id": key,
                      "category": categoryinfo.text! as String,
                      "description": descriptioninfo.text! as String ]

    refAttractions.child(key).setValue(attraction)
 }



@IBAction func backbtn(_ sender: Any) {
    dismiss(animated: true, completion: nil)
    }
}

此外，我已将firebase数据库中的规则更改为true以进行读取和写入。任何帮助将不胜感激。
