how to open viewcontroller in code

How to go to viewcontroller after certain actions, like here:

func requestForAccessToken(authorizationCode: String) {

        Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: nil)
            .responseJSON { response in

            switch response.result {
            case .success(let JSON):
                let response = JSON as! NSDictionary
                let accessToken = response.object(forKey: "access_token")!
                UserDefaults.standard.set(accessToken, forKey: "LIAccessToken")
                UserDefaults.standard.synchronize()
                ///here...
                DispatchQueue.main.async(execute: { () -> Void in
//                    self.dismiss(animated: true, completion: nil)
                    let secondViewController: LoginViewController = LoginViewController()
                    self.present(secondViewController, animated: true, completion: nil)
                })
            case .failure(let error):
                print("Request failed with error: \(error)")

            }
        }

    }

I create vc in storyboard and make vc class file. Maybe I must make something other.

If you are creatung a viewController in storyboard then you have to instantiate it with storyboard. Try this:

DispatchQueue.main.async(execute: { () -> Void in
    let secondViewController = UIStoryboard(name:"LoginViewController", bundle: nil.instantiateViewControllerWithIdentifier("LoginV‌​iewController") as? LoginViewController
    self.present(secondViewController, animated: true, completion: nil)
})

Hoping that you have named your storyboard as LoginViewController and provided with storyboardID as LoginViewController
