Test GameCenter on iOS 8 Devices

Apple has eventually released iOS 8 this week, but when I installed iOS 8 to my device my apps suddenly lost their Game Center connection. I guess you will have the same problem when you update. The thing is that apps that are published by other developers keep working, so I looked out for an iOS 8 specific bug in GameSharing, but there is none (At least none that explains that app behavior). The problem is that you have to enable a “Developer Mode” for Game Center on iOS 8. Doing that is not very complicated, you just have to turn on one slider, its located in Settings->Game Center->Developer->Sandbox. Once you activated Sandbox your apps should be able to communicate with Game Center again.
