Hello,
We have a lot of crashed related to Unity GameCenter.
Here is the crash log:

I have 2 functions using Unity GameCenter:

Code (CSharp):

1. IEnumerator SocialAuthenticate()
2.     {
3.         bool isAuthenticating = true;
4.         Social.localUser.Authenticate((success) =>
5.         {
6.             isAuthenticating = false;
7.         });
8.  
9.         while (isAuthenticating)
10.             yield return null;
11.  
12.         // do something
13.     }

Code (CSharp):

1. IEnumerator LoadLeaderboardScores(string userId, System.Action<bool> cb)
2.     {
3.         bool loading = true;
4.         bool ok = false;
5.         var leaderboard = Social.CreateLeaderboard();
6.         leaderboard.id = LEADERBOARD_ID;
7.         leaderboard.timeScope = TimeScope.AllTime;
8.         leaderboard.SetUserFilter(new string[] { userId });
9.         leaderboard.LoadScores((success) =>
10.         {
11.             loading = false;
12.             ok = success;
13.         });
14.  
15.         while (loading)
16.             yield return null;
17.  
18.         cb(ok);
19.     }

Note: I'm trying to avoid running my callback inside GameCenter's callback.
I'm using Unity 2018.4.12f1, could you please help?
Thank you!

I guess this crash related to Social.Authentication process.
I'm thinking of re-writing my own native GameCenter implementation :|

 

I'm also faced with this issue, have you had any luck @phuongnh ? It's a random crash so it's very hard to debug. I tried using lambda methods for the callback like other forum threads are suggesting and nothing seems to work ...

Like you said I guess there's no way around but to code our own GameCenter implementation.


EDIT: I just removed the LoadAchievements altogether. It kept crashing ... ¯\_(ツ)_/¯

 

@mmSimon: I write it myself. It's simple as I only need to save the high scores. And then these crashes are gone away, you should give it a try

 

How did you do that?

 

Yes @phuongnh, could you share with us what you did so that the issue was resolved. Also, I'm reading that the issue would be fixed in iOS 14, so, how could you be certain that the issue is resolved with your own handling of GameCenter?

Thanks in advance.
