drupal 8, how debug a class?

I want to train myself to use Drupal 8 (Im from drupal 7 =) ). So, I learned some symfony2 basics. Now, I would like know if there is a good way about the code debugging, I mean : Before with Drupal 7, I used the devel module for show the content of data (very usefull !). I try this module for drupal 8 but the dpm function seems not work in the class context.

Bu example, I use this code for alter some route :

<?php
namespace...
use...
...

class RouteSubscriber extends RouteSubscriberBase{
  public function alterRoutes(RouteCollection $collection){
    // What is the best way for display the $collection array ? like a dpm ? 
    dpm($collection); // doen't work, nothing appears in any page
  }

Thanks =)

If you're used to using the Devel debug functions like dsm() and dpm(), you would feel right at home using Devel Kint. Just enable the module Devel Kint and use it in modules or theme with kint($variables).

I would also look into using Xdebug and setting break points to debug at a deeper level.

Use debug() in Drupal 8. debug() will print the content of the variables as messages on the site. Alternatively, you can use a debugging tool like xdebug to examine your variables.
