macOS Interface builder fails to start

[iphonedude2008]

I recently updated to OS X 10.10 beta 6. I have Xcode beta 5 installed as well. Before I updated to the next OS X beta, Xcode was working fine. Now, when I open a storyboard file, it crashes saying

Details: Failed to determine the value for systemColors of UIColor.

What do I do?

I'm having the same problem as well. Downloading the Xcode 6 beta 6 to see if it fixes anything
