如何在 Xcode 10 中获取快速帮助? [英] How to get the Quick Help back in Xcode 10?

问题描述

升级到 Xcode 10 后，快速帮助信息仅提供所选类或结构的声明.

After I upgraded to Xcode 10 the Quick Help information only provide declaration of the selected class or structure.

有没有什么地方可以让我让它与 Xcode 9 中的一样?

Is there a setting somewhere that I can make it same as what it was in Xcode 9?

推荐答案

升级后我遇到了同样的问题，在执行选项单击时，函数签名是唯一显示的内容.当我删除 ~/Library/Developer/Xcode/DerivedData 以及 ~/Library/Caches/com.apple 中的所有内容时，快速帮助重新出现.dt.Xcode.顺便说一句，您需要先退出 xcode.希望这可以帮助.

I had the same issue after upgrading where the function signature is the only thing showing when doing an option click. Quick Help reappeared when I deleted everything inside ~/Library/Developer/Xcode/DerivedData as well as in ~/Library/Caches/com.apple.dt.Xcode. You need to quit xcode first btw. Hope this helps.
