Display number of players online for online matchmaking(GameKit)?

Hello, has anyone been able to implement in their game a way to display the number of players currently online in their game?. I thought up of this feature and thought it will be useful for players to find out if there is anyone currently online so that they don't waste their time trying to find a random online match. Any help will be greatly appreciated.

Kind regards, Jabir Abdi
