simple data insertion using realm swift

Question

I'm an newbie in realm-swift. Trying to do an simple data insertion in realm DB. I'm getting following warning:-

WARNING: An RLMRealm instance was deallocated during a write transaction and
all pending changes have been rolled back. Make sure to retain a reference
to the RLMRealm for the duration of the write transaction. 

Here is my code :-

import Foundation

class Dog {

    dynamic var name = ""

    dynamic var age = ""

}

import UIKit
import RealmSwift

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.



        let myDog = Dog()
        myDog.name = "puppies"
        myDog.age = "5"


        // Get the default Realm
        let realm = try! Realm()

        // Add to the Realm inside a transaction
        realm.beginWrite()


             realm.add(myDog)


        /*realm.add(myDog)
        realm.commitWrite()*/



    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

any help would be appreciated...
