So I just created a new project in Xcode and linked it with GameKit and I agree that the only visible change is the linking to the GameKit framework and the addition of the gamekit key to the plist file. I think I need to figure out how to specify entitlements in Xojo. There is a place to select an entitlements file in build settings but I’m not sure what format that would be and what it would need to contain to make everything work. Is there a resource that describes this?
