Apple GameKit Game Center Extension

Quite a few. An example:

Any solution to this?

The LuaHBuffer has a new constructor and a new way of defining ownership. I write “new” but it’s actually a pretty old change which no one has bothered contributing a fix for. Until now!

Here’s my fork with the fix: GitHub - britzl/extension-gamekit: Apple GameKit native extension for Defold

And the PR to the upstream repo: Changed LuaHBuffer constructor by britzl · Pull Request #4 · animonger/extension-gamekit · GitHub

Thank you @britzl .
I replaced the line in the library with the correction.

Would you happen to know what this error means and or how to fix it:

Wondering if there are any dependencies I may be missing. I am running this on an M2 Pro Macbook 16".

Ah, I only tested with an iOS build. I have updated my PR to support also arm64 macOS.
