How can I downgrade one of the storyboards that was created in xcode 6 to xcode 5? Note that I am using xcode 5.
You must use Xcode 6 to downgrade a storyboard. If you can't run it, you need to find a friend who can.
Open the storyboard in Xcode 6. In the File Inspector, find the “Opens In” menu and set it to “Xcode 5.1”. If the storyboard uses size classes, choose the size class to preserve. Save the file.
