Upon trying to open or create a XIB file, Xcode 6.4 just crashes:

I've uninstalled Xcode (including Xcode 7 beta) and the command-line tools, and tried reinstalling Xcode from the App Store but no luck. I'm on OS X 10.11 beta 6 but the lack of other crash reports makes me worry that there is an issue with my machine. What should be providing @rpath/IBCocoaTouchToolFoundation.framework/IBCocoaTouchToolFoundation?
Filed a report at rdar://problem/22125914 but a hacky fix would be helpful too so I don't have to use another computer just for Interface Builder.
