title: Get FBSDKLoginManagerLoginResult's email and name
body: <p>I am using Facebook custom login to get user's email and public profile but I only get this. Is there any else code that I have missed out? Most of the online tutorials are in Obj-C or outdated already. I am using Swift for this project.</p>
  
  <pre><code>RESULT: '&lt;FBSDKLoginManagerLoginResult: 0x7fe6f8c1d510&gt;' 
  </code></pre>
  
  <p>Here are my code for the custom button</p>
  
  <pre><code>let login = FBSDKLoginManager()
      login.logInWithReadPermissions(["email", "public_profile"]){ result, error in
          println("RESULT: '\(result)' ")
  
          if error != nil {
              println("error")
          }else if(result.isCancelled){
              println("result cancelled")
          }else{
              println("success")
  
          }
      }
  </code></pre>
