I like to add Game Center achievements to my app.
For testing purposes I created one leaderboard list and two achievements in App Store Connect and enabled them in my app.
Then I authenticated the local player in Game Center and called the Dashboard.
What I see is that one leaderboard is available. Fine. However, 0 / 0 achievements. No achievements available. I assume that I should see 0 / 2 achievements but I have no idea, why they do not show up.
I also tried to report an achievement with GKAchievement.report and it seems to report without error.
But when I try to load any achievement, I get an error that no achievement can be found.
Any ideas what I did wrong or forgot to do?
