Alter drupal 8 views in for each row

Question

I have a view and I want to alter the output in each row.
So I have tried hook_views_pre_render(), and hook_preprocess_views_view(), but with no luck. In both of the above hooks I got data in $view->result, but there seems to be no way to change the rendered output.

Answer 1

After a long a research and development, I came to an conclusion that this could be the answer:

foreach ($view->result as $result) {
  $result->_entity->set('field_name', array(0 => 'value'));
}
