Insert instead of update in firebase - ios

Question

I'm trying to insert new values into Firebase Realtime Database. But every time I "register" a new user, my database data is getting replaced by the new one. I'm totally confused on how I can do this different.
This is my code..
//Create a new user with txtfield email & password
Auth.auth().createUser(withEmail: email, password: password) { authResult, error in
//Printing error if any
if error != nil
{
print(error as Any)
return
}
//Getting database reference
let ref = Database.database().reference()
//Values to insert into database
let values = ["Username": self.username, "Email": self.email, "Name1": self.name1, "Name2": self.name2, "Name3": self.name3, "Name4": self.name4, "Name5": self.name5, "Name6": self.name6, "Dog1": dog1, "Dog2": dog2, "Dog3": dog3]
//Updating the child values
ref.updateChildValues(values, withCompletionBlock: { (err, ref) in
//Printing error if any
if err != nil
{
print(err as Any)
return
}
//Succeded if no errors
print("Saved user successfully in Firebase database!")
})
And I assume the problem is at
ref.updateChildValues(values, withCompletionBlock: { (err, ref) in
But I've no idea how I can replace this. So to make it short.
Every time I create a new user, the database data is getting replaced. And I basically want it to create a new "row" for each user.

You need to insert the items under a child like users/userID
guard let firUser = authResult.user else { return }
let userID = firUser.uid
let ref = Database.database().reference()
let user = ref.child("users/\(userID)")
user.updateChildValues////
Database
