[CI3 session on Safari]

I got a problem with the CodeIgniter session when users use Safari from PC or Tablet. On Google Chrome and Firefox Dev Edition is working perfectly i think the problem is related with Safari.

That's my code for the session after the success log-in:

$logged_in = array(
'username' => $out[0]['username'],
'user_id' => $out[0]['id'],
'logged_in' => TRUE
);

$this->session->set_userdata($logged_in);
$this->session->set_flashdata('user_data',$logged_in);

redirect('social/userprofile/'.$out[0]['username']);

Any suggestions?
