我想更改用户个人资料图片，但我的所有功能都是删除实时数据库中的 child("profileImageUrl")。新的个人资料图片按预期上传到存储，但孩子没有被更新而是被删除。我还没有找到解决方案，有人可以帮我吗？

这是我的功能：

func updateProfileImage() {
    guard imageChanged == true else { return }
    guard let currentUid = Auth.auth().currentUser?.uid else { return }
    guard let user = self.user else { return }
    
    Storage.storage().reference(forURL: user.profileImageUrl).delete(completion: nil)
    
    let filename = NSUUID().uuidString
    
    guard let updatedProfileImage = profileImageView.image else { return }
    
    guard let imageData = updatedProfileImage.jpegData(compressionQuality: 0.3) else { return }
    
    STORAGE_PROFILE_IMAGES_REF.child(filename).putData(imageData,metadata: nil) { (metadata,error) in
        
        if let error = error {
            print("Failed to upload image to storage with error: ",error.localizedDescription)
        }
        
        STORAGE_PROFILE_IMAGES_REF.downloadURL(completion: { (url,error) in
            USER_REF.child(currentUid).child("profileImageUrl").setvalue(url?.absoluteString,withCompletionBlock: { (err,ref) in
                
                guard let userProfileController = self.userProfileController else { return }
                userProfileController.fetchCurrentUserData()
                
                self.dismiss(animated: true,completion: nil)
            })
        })
    }
}

我像这样存储用户数据：

let dictionaryValues = ["name": fullname,"username": username,"profileImageUrl": profileImageUrl]

let values = [uid: dictionaryValues]

Database.database().reference().child("users").updateChildValues(values)
