In order to use Game Center in an app, that app needs to have the “gamekit” key added to its info.plist file. According to the release notes on this feature:
Any items USER plists create that duplicate keys the IDE creates will be over written by the IDE (basically you can't replace or augment entries the IDE creates)
Only top level keys are dealt with (keys that are immediately children of PLIST > DICT in the Plist XML format)
In order to add this key so that the app works properly with Game Center it must be added to the UIRequiredDeviceCapabilities array which Xojo already creates with the “armv7” key. What is the best way to set the “gamekit” key in the info.plist file so that the app works correctly? Or do I need a feature request?
