Integrate GameLift Realtime Client in a native iOS Swift Project?

Thank you for reaching out us regarding the above query. I would like to share that as of now unfortunately GameLift doesn't support Swift officially, which means that we cannot use Gamelift SDK with native IOS swift project. However I would like to thank you for allowing us to improve the service by raising this query. I have passed this feedback to the Gamelift internal team and requested them to consider this as a feature request. While I am unable to comment on if/when this feature may get released, I request you to keep an eye on our What's New and Blog pages for any new feature announcements.

Having said that, in case you face further challenges, please feel free to open a support case with AWS using the following link.
