ios - FirebaseIOS : Use of Undeclared Type 'DatabaseReference'

Question

不好意思问了个奇怪的问题

昨天我不得不更新我的 firebase pod，在那之前一切都很好，但在那之后，我再也无法检索数据了

这是我的代码

    //  let userID = FIRAuth.auth()?.currentUser?.uid
    var rsef: DatabaseReference! // undeclared

    rsef = Database.database().reference() //. undeclared

我看了官方的firebase setup instructions，那些是对的，但我不知道为什么它说undeclared

作为引用，这是我的完整代码

 ref.child("KurdishRsta").child((FIRAuth.auth()?.currentUser?.uid)!).childByAutoId().queryOrderedByKey().observe(.childAdded, with:
        { (snapshot) in
            print("Database\(String(describing: snapshot.value))")
        let value = snapshot.value as? NSDictionary
        let FullRsta1 = value?["Rsta"]
        let FullMeaning1 = value?["Meaning"]





        self.RetrivedRsta.insert(RstasFromFirebase(FullRsta:FullRsta1 as! String ,FullMeaning : FullMeaning1 as! String), at: 0)

        self.tableview.reloadData()



    })
}

请务必在您调用 DatabaseReference 的文件中添加 firebase 数据库的导入，而不仅仅是单独导入 Firebase

 import FirebaseDatabase
