title: Firebase "rules" does not work at all
body: <p>I made firebase rules as below, but <code>read</code> and <code>write</code> operations are both available from client.</p>
  
  <pre><code>{
      "rules": {
        ".read": false,
        ".write": false
      }
  }
  </code></pre>
  
  <p>The Authentication is "Custom".<br>
  Could anyone suggest me what is wrong?</p>
  
  <h2>Additional Information</h2>
  
  <p>I made iOS client with official Firebase library as below.</p>
  
  <pre><code>let firebase = Firebase(url: FIRE_BASE_URL)
      firebase.authWithCustomToken(FIRE_BASE_AUTH_TOKEN) { (error, data) in
          if let data = data {
              debugPrint("***** Log in complete *****")
              let ref = firebase.childByAppendingPath("test/")
              let dic = ["key" : "hoge"]
              ref.childByAutoId().setValue(dic){ (error, firebase) in
                  if let key = firebase.key {
                      /* This code reaches here, which is not expected behavior. 
                        (Of course, new data was added to firebase.) */
                  }
              }
          }
      }
  </code></pre>
