Storyboards opened in Xcode 8 no longer open in Xcode 7

Opened my app in the Xcode 8 beta, then tried to open it in Xcode 7, only to receive this error:


"This version does not support documents saved in the Xcode 8 format. Open this document with Xcode 8.0 or later."


Any one know of a fix to get my storyboard working in Xcode 7 again?
