Not really. Many versions of Xcode will use a different versioning in the storyboard. If you open one version of your code in a newer version of Xcode, occasionally, the storyboard versioning is updated to the new version of Xcode and you can't change it back from an older version of Xcode or even open the storyboard.
I've run into this when opening a project in 4.3 a while back and had to rebuild my entire set of storyboards since there was no explanation what was happening.
Just letting you know that it's not always as easy hinted to run multiple version of Xcode on the same machine or using the same project. Duplicate your project and use the dup before moving to a new version of Xcode.
