与IOHIDFamily的神秘控制台错误
对于我的一个项目，Xcode控制台中的这个错误信息每当我在iOS模拟器中运行构build时都会发生。 这已经发生了一年多了，我认为它最终会消失，更新Xcode。 我已经取消和重新链接了所有的框架，我没有明确地调用IOHIDFamily的任何东西，不pipe这是什么！ 它似乎没有影响我的程序执行，但我真的很想弄清楚为什么它每次都转储所有这一切。

在后一种情况下，您的应用程序会链接到Mac上的mach-o文件（除非有人build议您只与SDK程序集链接，而不是本机Mac链接），但是这会真的减慢构build速度，不再是可用的选项我相信最近的Xcode版本）。
显然，其中一个mach-o文件 – IOHIDFamily扩展名，如果GameKit.framework被链接为库，似乎被链接 – 并不是专门为iOS模拟器构build的。 因此，消息。 据我所知这是一个确认的苹果错误，并将在某个时候由苹果修复。
这只是iOS模拟器的一个问题，可以安全地忽略。
Vinnie发布了这个解决scheme
尝试将IOS构build选项：链接器选项设置为“仅链接SDK程序集”，为我解决了它

禁用Game Centerfunction会为我删除这些消息。 在您的项目上，select所需的目标并转到function 。
在新的Xcode 7.2上，这些消息不再显示。
但是我有了与SpriteKit相关的新消息 ：
CUICatalog: Invalid Request: requesting subtype without specifying idiom
CUICatalog：无效请求：请求子types而不指定成语
当我在iOS代码中遇到这个问题时，是因为我的两个类包含一个import基础。 新文件默认为OS X /源/ Swift文件，我没有注意到。
删除这些import消除了这个问题。
我通过继续常规选项卡解决了这个问题，取消了“ 需要全屏”选项来禁用iPad多任务。 但是，如果多任务处理不当，可能会出现validation错误！
