this resolved bug and you do not yet see a matching new report.
Steps to reproduce:
1. Open VS and connect to lion build host.
2. Open or create iOS storyboard application.
3. Open MainStoryboard.Storyboard file in VS
Actual result: File does not render in VS and giving exception. This is happening when connected to Lion(It support Xcode below 5.0). If user is connected to ML or Maverick and having Xcode below version 5.0 in that case, storyboard file opens successfully in VS.
Expected Result: Storyboard file should open successfully in VS if connected to lion build host.

Other than that, we don't support any Xcode older than 5, so Lion is not expected to work. We should not be crashing mtbs though, so if mtbs is crashing we should figure out why.
I'll make sure we properly error out if the detected xcode is < 5.
We added handling so that if an old Xcode is detected we disable the designer. This matches what we do in Xamarin Studio:
I have checked this issue with following builds
Xamarin for VS 2.00.110
I am getting proper error when Xcode is below 5.0. I am getting error "The iOS Designer requires Xcode 5.0 or higher. Visual Studio is currently configured to use Xcode 4.x.x. You must either upgrade Xcode or configure Visual Studio to use a different Xcode installation in the Apple SDk Settings section of the Preferences"
