Xcode 6在OS X 10.10上崩潰，異常名稱為：IBAssertionFailure

Question

當我在界面生成器中復制並粘貼uitableview單元時，它工作正常。 但是在第二天，當我啟動Xcode時，它崩潰並報告了，

與Interface Builder Cocoa Touch Tool通信時遇到錯誤。 如果您選擇針對此問題提交崩潰報告或Radar，請在Console.app中查看“ Interface Builder Cocoa Touch Tool”的崩潰報告，並將其內容包括在崩潰報告中。

異常名稱：IBAssertionFailure異常原因：ASSERTION FAILURE：containsTableView原因：任何添加到布局引擎的表格視圖單元都應包含在表格視圖中，以便獲得正確的指標

Answer 1

Storyboard文件中有錯誤，我只是從Finder中刪除Main.Storyboard文件，然后打開Xcode。 Xcode比正常運行。
