It is a newly created iPhone Project. Nothing has been changed
Comment 2 Alan McGovern 2013-08-29 17:45:02 UTC
Can I just confirm that you're using Xcode 4.6.x and not a newer version? We only support Xcode 4.6.0 -> 4.6.3 with our current releases. Using other  Xcode versions can result in this error.
Comment 3 Alex Corrado [MSFT] 2013-09-05 19:48:29 UTC
This issue should now be fixed. Please try again with Xamarin Studio 4.1.10 from the alpha channel.
Comment 4 Atin 2014-03-26 08:07:34 UTC
I have checked this issue with:

XS 4.2.4(build 266)
ML 10.8.4

We are successfully able to open storyboard in iOS designer without any error.
Hence marking this as Verified.
