Is anyone else having issues with the storyboard editor in Alpha 4.1.11? Even if I create a new single view storyboard iPhone application, when I try and open the storyboard in XS, it spins for quite a while and then errors. (I have attached the very long error message to this post). My collegue is having the same issue.
I'm fully up to date on patches, XCode 5.0 is installed, emulators updated etc.
