How and where should we use \Swoole\Timer ?

When i use it in ServiceProvider:

class AppServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        \Swoole\Timer::tick(10 * 1000, function () {
                //
        });
    }
}

I'll get the following error when i ran: php artisan serve:

In Server.php line 51:
                                                                                                  
  Swoole\Server::start(): eventLoop has already been created, unable to start Swoole\Http\Server

You can't launch an event loop (timer) before starting the server. You need to start the timer after the server worker is running by listening Hyperf\Framework\Event\AfterWorkerStart event.

Also, most of the time you shouldn't call Swoole's functions directly. Instead, use a wrapped timer provided by Hyperf framework Hyperf\Coordinator\Timer.

@albertcht Ok but another problem is that, there are 8 workers, each of them run the timer, Couldn't we just run one timer in all workers?

Nevermind the event i used is MainWorkerStart
