Laravel - Call to undefined method Swift_SmtpTransport::newInstance() - php

Question

I'm using Swiftmailer to send email. I had installed
+ "guzzlehttp/guzzle": "^6.3"
+ "swiftmailer/swiftmailer": "^6.0".
I create controller and route for it. But it has issue "Call to undefined method Swift_SmtpTransport::newInstance()". Please check my code and guide me how to fix it? Thanks so much
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Mail;
use Swift_Mailer;
use Swift_MailTransport;
use Swift_Message;
class EmailController extends Controller
{
public function sendEmail(){
// Configuration
$smtpAddress = 'smtp.zoho.com';
$port = 465;
$encryption = 'ssl';
$yourEmail = 'ptc#gmail.com';
$yourPassword = '********';
// Prepare transport
$transport = \Swift_SmtpTransport::newInstance($smtpAddress, $port, $encryption)
->setUsername($yourEmail)
->setPassword($yourPassword);
$mailer = \Swift_Mailer::newInstance($transport);
// Prepare content
$view = View::make('email_template', [
'message' => '<h1>Hello World !</h1>'
]);
$html = $view->render();
// Send email
$message = \Swift_Message::newInstance('Test')
->setFrom(['ptc#gmail.com' => 'Our Code World'])
->setTo(["hik#gmail.com" => "mail#mail.com"])
// If you want plain text instead, remove the second paramter of setBody
->setBody($html, 'text/html');
if($mailer->send($message)){
echo "Check your inbox";
}
echo "Something went wrong :(";
}
}

Answer 1

Found in GitHub issues, for SwiftMailer "^6.0"
::newInstance() method has been deprecated, along with
Swift_MailTransport.
Try to change:
\Swift_SmtpTransport::newInstance()
\Swift_Mailer::newInstance()
to:
new \Swift_SmtpTransport();
new \Swift_Mailer()

Don't overcomplicate things.
You are rewriting something that comes bundled with laravel.
https://laravel.com/docs/5.5/mail
No need to setup swiftmailer yourself, just use the laravel classes and set the smtp credentials on
config/mail.php
It can be as easy as
Mail::raw('Text to e-mail', function($message)
{
$message->from('us#example.com', 'Laravel');
$message->to('foo#example.com')->cc('bar#example.com');
});
Or you can go fancy and use a view to make your template.
Mail::send('emails.welcome', $data, function($message)
{
$message->from('us#example.com', 'Laravel');
$message->to('foo#example.com')->cc('bar#example.com');
$message->attach($pathToFile);
});
