I have had the same issue a couple of times. Both times it started when I was loading an IBDesignable nib onto the storyboard when the nib was not able to fit on the view (ie I had a button off of the UIView but still in the nib). Once I fixed that Xcode still gave me errors so I restarted Xcode until it randomly stopped giving me the error.

I hope this helps.

UPDATE: I just killed all processes named "Interface Builder Cocoa Touch Tool", restarted Xcode and the error went away. Don't know if this will always work or not.

You could select your custom view in Interface Builder and then use Editor, Debug Selected Views. It will launch so-called IBDesignableAgentCocoaTouch debug session when all breakpoints (including exception breakpoints) work and you could exactly identify the place your view crashes.
