The document “(null)” requires Xcode 8.0 or later

Question

I saw a similar question for 6.0

Building a project in Xcode5.1 that was modified in Xcode 6 GM for testing older versions of iOS

The solution there was to look at the storyboard source and find where the constraints were set to the margin and not the superview and change that. I looked through my source code in 8.0 a and did a search for constraint but didn't find any.

Is there something else that can throw this error?

Answer 1

We can solve this Using Xcode 7 , right-click on the file(xib or storyboard) and open as source code. Then search ( Command + F ) for: minToolsVersion="8.0"and change it to 7.0.

Then open the file as interface builder xib document.
