We are excited to announce the release of GKNativeExtensions, a small native utility library made to support iOS Cloud save by using the apple-recommended GKSavedGame API. The utility library currently supports the following operations: Fetching existing save games Saving a game by name Loading a game by name Deleting a game by name Resolve multiple conflicting saves Registering a callback to be called when a conflict is detected Registering a callback to be called when a save occurs on a different device (not properly tested) The project can be found on Github: https://github.com/dark-1-games/GKNativeExtensions It is licensed under the Mozilla Public License 2.0. This should technically work on OSX, but our focus has been iOS. Please let us know if you get it working on OSX. The library was made to be integrated in our upcoming cross-platform integration system, DarkCPS, for which we're currently looking for testers https://forum.unity.com/threads/darkcps-game-services-simplified-looking-for-testers.697136/ Comments and feedback are welcome!
