I set all the itunes connect stuff and the leaderboard ID is correct so I decided to open a new Xcode project and write just the game center code in Swift and it worked, the leaderboard appeared and work perfectly.

我设置了所有的itunes connect功能，并且排行榜ID是正确的，所以我决定打开一个新的Xcode项目，用Swift编写游戏中心代码，它成功了，排行榜出现了，并且运行得很好。

I don't know if it's a problem because of Objective-c or what please can anyone help me what it can be so I don't have to write all the app code from Objective-C to Swift?

我不知道这是不是因为Objective-c的问题，或者有谁能告诉我它是什么，这样我就不用把所有的应用代码从Objective-c写到Swift了?
