I downloaded Xcode beta and opened my existing project to see how it works with Xcode 8 beta (I opened Storyboard file from Xcode 8).
Now when I open my project from Xcode 7.3 I am not able to open storyboard file , it gives me following error
This version does not support documents saved in the Xcode 8 format. Open this document with Xcode 8.0 or later.
What should I do to revert back, as I want to continue working on Xcode 7.
In Xcode 8 I was prompted to select device and I selected iPhone 6S, I think that part is somehow responsible for storyboard file not opening in Xcode 7
I have figured it out:
Open your Storyboard in Xcode 8.
Click on the File Inspector.
In Interface Builder Document section, select Opens In "Xcode 7.x" instead of "Latest Xcode (8.0)", as in following screenshot:
On doing this, you will get an alert saying "Saving for Xcode 7.x will close your document and data for Xcode 8.0 features will be removed."
Click Save and Close and you will be able to open storyboard in Xode 7.x.
