Wordpress / PHP: Problems keeping variable $ _SESSION when changing page

I have the following code in the same file:

add_action( 'init', 'iniciaSessao', 1 );
function iniciaSessao() {
    if(!session_id() ) {
        session_start();
    }
}

function info() {
$_SESSION['nome'] = 'meu nome';
}

info();
//session_regenerate_id(true);
wp_redirect($minhaUrl);
exit();

When you go to the homepage of the site (where you are redirecting) and use print_r($_SESSION['nome']); , the information set does not appear.

NOTE: The following error message appears when uncommenting session_regenerate :

  

session_regenerate_id (): Can not regenerate session id - headers already sent
