Try the following:

let userId = Auth.auth().currentUser?.uid else { return }
let docRef = db.collection("users").document(userId)
docRef.getDocument(source: .cache) { (document, error) in
  if let document = document {
    let name = document.get("firstname")
    print("Cached document data: \(name)")
  } else {
    print("Document does not exist in cache")
  }
}

You are using cloud firestore but in your code, you are using the Realtime database. You need to check the following docs related to cloud firestore:
