to get session data you need to do, $this->session->userdata('item'), and check for its value, change it to:

function guestcart(){        
    $session = $this->session->userdata('seed_key');
    if(!empty($session)){            
        echo 'Session exist ';        
    }  else {     
        $seed = 132;   
        //set the session data    
        $session = $this->session->set_userdata('seed_key', $seed);
        echo 'Session created';
    }
}
