Firebase Database Authentication Swift

I implemented the log-in and registration views for the Authentication via Firebase. Then how can I authenticate to my database? I changed the rules and I put: 

{
  "rules": {
    "users": {
      "$uid": {
        ".write": "$uid === auth.uid"
      }
    }
  }
}

I also wrote the code for obtain the User UID, but how can I say to my database that I'm authenticated?

PS: I need the example in Swift.

Swift 5 Just for Authentication and then use your own code for extension 

 let credential = PhoneAuthProvider.provider().credential(
        withVerificationID: FireBaseverficationID,
        verificationCode: "your device code")

 let defaults = UserDefaults(suiteName: "group.Company.AppName")
 let encodedData = NSKeyedArchiver.archivedData(withRootObject: credential)
    defaults?.set(encodedData, forKey: "firebasecredential")

After this in your Extension File decode this Defaults Value and use Credential for SignIn

let decoded = UserDefaults(suiteName: "group.Company.AppName")?.object(forKey: "firebasecredential") as! Data
    let credential = NSKeyedUnarchiver.unarchiveObject(with: decoded) as! PhoneAuthCredential

//MARK: - If user already login with credential
    let userid = Auth.auth().currentUser
    if userid == nil{
        Auth.auth().signInAndRetrieveData(with: credential) { (authResult, error) in
            if error != nil {

                return
            }
            else
            {
                //MARK:- Your desire code After Login
            }
        }
    }else{
        //MARK:- Your desire code if User already Login
    }

try the following format:

cloud firestore

  service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

realtime database

// Checks auth uid equals database node uid

// In other words, the User can only access their own data

{
  "rules": {
    "users": {
       "$uid": {
         ".read": "$uid === auth.uid",
         ".write": "$uid === auth.uid"
       }
     }
   }
}
