Bug GKLocalPlayer.Local.FetchItems() Error on Unity

I setup everything correctly for adding Apple GameCenter so I can use Cloud Save. On device, I successfully login and it shows the banner.

I get this error when the next line of code is called.

Code (CSharp):

1. var fetchItemsResponse = await GKLocalPlayer.Local.FetchItems();

Code (CSharp):

1. Thread 1: EXC_BAD_ACCESS (code=257, address=0x2)

Is there a fix coming soon?

Thanks

 

I'm having the same problem as you, except no Thread 1: EXC_BAD_ACCESS (code=257, address=0x2) error, it just crashes and cuts connection from the device to XCode

 

nvm, I have the error on another device i tested

 

I have the same problem,
fetchItems()
OnSuccess()
Thread 1: EXC_BAD_ACCESS (code=257, address=0x2) error, it just crashes when cuts connection from the device to XCode
if not cut connection, it will keep stay in this error line in Xcode
using Unity 2021.3.9f, build on iOS,
manually modified manifest.json to use unity authentication 2.4.0
using Apple Game Center plugin for unity

 

For anyone looking for a solution look at the bottom of this post. Someone posted a git where they fixed it.

He said he fixed the pointer thing in that branch but the callback still not working actually

 

Stuck in this problem for 2 weeks already, thanks for finally someone related try to handle it

 

It works for me

 

I also have the same error and so I could not use the apple plugin.

I found another path.
First I used Social.localUser.Authenticate();
Social.localUser.id - is TeamPlayerID;

then I used code from this link https://gist.github.com/BastianBlokland/bbc02a407b05beaf3f55ead3dd10f808

So I got:
publicKeyUrl, signature, salt and timestamp

And it works perfectly. Authorization on the Unity side works without any problems.

 

Is there any update on this issue?

 

People here are saying that this git branch is working properly. I still have to give it a try as soon as I can.

I confirm. It's working. It's impossible to select target platforms while building tars though.

I'm nonetheless waiting for the official release.

EDIT: I'm having troubles when I switch back to Android. Unity is building the Apple plugins for Android as well and this creates problems. It seems I cannot deselect the Android platform from the plugin inspector: even if I select only iOS and apply changes, as I try to build the .apk selection are resetting to "Any platform".
