更新: App Store 现在有一个新版本 (12.0.1) 可以解决这个问题.

Update: There's now a new version (12.0.1) in the App Store that fixes this issue.

我在使用 App Store 中的版本时遇到了同样的问题.此 Apple 论坛主题中的人报告说，在下载 GM 时不会出现这种情况来自 Apple 的开发者资源，尽管构建标识符完全相同.

I'm experiencing the same when using the version from the App Store. People in this Apple Forums thread are reporting that it doesn't occur with the GM download from Apple's developer resources, despite the build identifiers being exactly the same.

有趣的是，我可以确认在我删除它以支持 App Store 版本之前，我能够在 GM 版本中使用文档.因此，在 App Store 版本修复之前，这实际上可能是一个可行的解决方法.

Anecdotally, I can confirm that I was able to use documentation in the GM version before I deleted it in favor of the App Store version. So this may in fact be a viable workaround until the App Store version is fixed.
