Xcode 7 crashes every time it is opened

Question

After the upgrade, Xcode 7.0.1 Im will not be able to open my workspace, every time it crashes. After reading all this text, I understand its location of the collection view stream and some negative value. Let's say I have no chance to return to Xcode 6. Does anyone have a similar problem or know how to fix this?

an exception:

negative sizes are not supported in the flow layout

about my workspace:

using

• cocoapods
• storyboards
• automatic layout (clean layout in some files)
• Size classes not sorted

OS OS X 10.11 (macosx10.11):

Here is the crash log:
