I have given +1 to @MarkSzymczyk
as it pointed me in the right direction, but as it is a little bit old compared to the new xcode 5
I thought I would give an up-to-date answer.
I came across this issue where I was getting
This document "XXXXX.storyboard" could not be opened. Please use a newer version of Xcode. Consider changing the document's Development Target to preserve compatibility.
when I had looked at my project in xcode 5
and went back to xcode 4.6
. The way to solve this is slightly different from the old xcode
. I had to load the project back up in xcode 5
and navigate to the storyboard in the interface builder. In there there is now an "Interface Builder Document" section instead of the "Document Versioning" section. Under there, there is an option to change what version of xcode
you would like to open in. All you need to do is change back to xcode 4.x
.
I don't want to take away from the other answer as it is correct still I just want to expand on that answer.
