I’m attempting to get this apple sample to work, but I’m having trouble running the app on more than one device.

I only have one phone; the second one belongs to my wife. When I try to run the app on her phone, I can’t add my developer certificate, so I’m unable to run the app.

I’ve tried logging into GameCenter on the simulator, but I can’t invite myself to the match. I’m not sure if there’s something wrong with the code or if it just doesn’t work with the simulator.

I there any way to run two instances of app at a time on different devices? Do I need to check GameCenter checkbox in app store connect? And basically how do you test your apps which are using Game Center multiplayer features?

Thanks
