I recently upgraded to Xcode 7.3. I found that loading up the storyboard can take anywhere from 5 to 10 minutes to complete(and may sometimes result in a crash). I've restarted my Mac several times. I uninstalled Xcode and reinstalled it to no avail. I then cleared my Derived Data as well as com.apple.dt.Xcode to find that this did not help either. Is anyone experiencing a similar issue and possibly has a solution?
