试试这个：

let loginVC = storyboard?.instantiateViewController(withIdentifier: "LoginViewController") as! LoginViewController
if self.emailTextField.text == "" 
{
    loginVC.str = "Hello"
} 
else 
{
    loginVC.str = self.emailTextField.text!
}
navigationController?.pushViewController(loginVC, animated: true)

<强> LoginViewController

class LoginViewController: UIViewController 
{
    var str:String! = nil
    override func viewDidLoad() 
    {
       super.viewDidLoad()
       self.userName.text = str
    }
}
