Weddings and weddings

Question

I work with a multiplayer game using Swift, SpriteKit and Firebase.

This is the first time I use multiplayer mode and GameKit , so I do not understand the concept of matchmaking. I read the Apple documentation, but to be honest, it's not clear, it tells me what it can do in real time and shows some code in objective-c.

I searched for dating in swift for a long time, and I found this .

I know that every match starts with matchRequest, but I don’t know what to do after that.

How does matchmaking work? What methods should I use? Does anyone know where I can find an example?
