Is Game Center Multiplayer Friends broken in IOS 9? [closed]

Question

I created a game that uses real-time multiplayer programmatically. It was originally targeted to towards IOS 8 devices. Recently after migration to IOS 9, Game Center has caused a lot of problems. The main issue I cannot resolve is Inviting a friend in multiplayer (for testing).

From IOS 8 to IOS 8. Auto match works and Friend invitations work But from IOS 9 to IOS 9. Auto match works and Friend invitations do not work anymore.

If any of you have managed to make Game Center invitations work on IOS 9. Please guide me to the right path.

What I currently know:

• This is a game center issue because I have tested the issue on a different app from scratch. Which caused the exact same problem
• I am using accounts that are registered as internal testers on iTunes connect Testflight
• IOS 9 has merged sandbox with production
• When I send invites it doesn't get received on other device (IOS 9 only)
• Notification are turned on both devices and Push Notifications are enabled for the app
• Restarting devices didn't resolve anything. I have tested both IOS 9.0.0 and 9.0.1
• I am aware that 9.0.2 has game center loading issues which I would like to avoid for the time being

UPDATE - 9/10/15 After they turned off sandbox for IOS 8. Auto-match has started working between IOS8 and IOS9. But the friend still seems to be an issue. The friend has also stopped working for me on IOS 8.

Game Center callback seemed to run on a different thread and caused a 80% chance of a crash on connect. The solution was to run the code on the main thread and it was resolved. But the threading issue didn't fix the friend bit.

After trying to start match with a friend request it throws an error as follows:

Error Domain=GKErrorDomain 
Code=3 
"The requested operation could not be completed due to an error communicating with the server."

        }
    }
}

Answer 1

From my recent experience, yes it is currently broken or at least has serious problems. Creating new matches over Game Center only works some of the time. I also get the code=3 error. However, it does work some of the time for me. It appears (for me) that new matches are successfully created and delivered when 1) I get no error after sending the first turn of the match and 2) I am able to load matchData and it is the correct data.

Yup it is broken for testing. And after putting a test game on the store it seems perfectly fine. I assume you were able to test the 'turn-based' version a little bit but for 'real-time' it is a nightmare. – Vaas

Yes, my answer is based on a test game still not on the app store. It will be a pleasant surprise if everything works smoothly when the app goes live. – Kiefer

@Vaas By 'in the store' do you actually mean live and downloadable by everyone, or a test flight prerelease version? – Troth

it means downloadable – Vaas

Still broken in 9.2 beta 1, as far as I can tell. – Troth
