ios - Xcode 7 每次打开时都会崩溃

Question

更新 Xcode 7.0.1 后，我无法打开我的工作区，每次都崩溃。阅读完所有这些文字后，我明白这是关于集合 View 的流布局，以及一些负面值(value)。假设我没有机会回到 Xcode 6。有没有人有类似的问题，或者知道如何解决这个问题？

异常(exception):

negative sizes are not supported in the flow layout

关于我的工作区:

使用

cocoa bean

Storyboard

自动布局(某些文件中的纯布局)

未检查尺码类别

操作系统
OS X 10.11 (macosx10.11):

这是崩溃日志:
