Creating a project in Xcode5.1 that was modified in Xcode 6 GM to test earlier versions of iOS

Question

My application supports at least iOS6 using the Xcode5.1 storyboard.

After I did some work in Xcode 6 GM, I need to test on iOS 6 Simulator. Xcode 6 GM does not have iOS 6 Simulator. So, I opened my project in Xcode 5.1.

But he cannot build. I can’t even open the storyboard in Xcode5.1.

The navigation bar says:

Main_iPhone.storboard
Interface Builder Storyboard Compiler Error
The document"(null)" requires Xcode6.0 or later.

And when I click on it, an invitation appears

The document "Main_iPhone.storyboard" requires Xcode 6.0 or later.
This version does not support constraints to layout margins. Open this document with Xcode 6.0 or later.
