The document "XXXX.xib" could not be opened. Could not read archive - xcode

Question

After opening my project in the Xcode5 developer preview, errors appeared against a few .xib files when I tried to open the project in Xcode 4.5. The error text was:
The document "XXXX.xib" could not be opened. Could not read archive.
Please use a newer version of Xcode. Consider changing the document's Development Target to preserve compatibility.
The project's development target in Xcode5 appears to be iOS 5.0.
Looking at the source code of the .xib files with errors, it is clear that the .xml structure for .xib files in Xcode5 has changed quite dramatically, and it needs to be reformatted to be backwards compatible.
Is there a way to set development targets for specific .xib files? Does anyone know how this error can be resolved?
Many thanks.

Answer 1

Just open Storyboard in XCode 5, into right panel and "File Inspector" tab do:
edit your "Interface Builder Document" like follow:
Save it and open in previous XCode.

Answer 2

First of all open project with Xcode5. and then
select XXX.xib find Interface Builder Document
Opens in Xcode 4.6(if is 5.0)
close project
open it with 4.6

Answer 3

A better and easier solution that works even if your project isn't under source control can be found here (mine):
Just installed xcode 5 and have missing storyboards
Hope that helps.

Answer 4

It's a current problem when you open your Xcode 4.6 project with the new XCode 5.
To reuse correctly your XIB with Xcode 4.6 :
1 Open your project with XCode 5
2 Select your Xib to restore
3 In the File Inspector Section, in "Interface Builder Document",
select Xcode 4.6 in the Development's version of Document Versioning
4 Build and close
5 Reopen your project with XCode 4.6
It's possible to have some regression with elements width & size in your XIB, but it was restored successfully.
Cheers,

Answer 5

well obviously you created your project prior to the new xcode developer preview. then you tried opening your project with the new DP and boom, it automatically changed everything in your xibs to be able to present your xibs in a higher version. easy to fix. with your xcode 4 ios 6 open the same project, then right click on the name of the xib that is not opening and select source control and from there select discard changes. that should return the xib back to the shape it was before you opened it with the new xcode DP.
let me know if you need more help but that should take care of your problem.

Answer 6

First you have to open your's project with newer version of Xcode.
Right click on XXX.xib file and select "Show File Inspector."
Go to Interface Builder Document.
Change Development option with older version of Xcode.

Answer 7

Once I used to manage a project with XCode 5 xibs in XCode 4. I split xibs for each XCode version and made this build script that compiles xib to nib and place that nib them inside the app
#get SDK version
SDK_VERSION=$(echo $SDKROOT | sed -e 's/.*iPhone\(OS\)*\(Simulator\)*\([0-9]*.[0-9]*\).sdk/\3/')
if [ $SDK_VERSION == '7.0' ]; then
echo 'Current SDK is 7.0'
ibtool --compile ${TARGET_BUILD_DIR}/${TARGET_NAME}.app/output.nib ${PROJECT_DIR}/ProjectFolder/input.xib.xib
echo 'Copied nibs to' ${TARGET_BUILD_DIR}/${TARGET_NAME}.app
else
echo 'Current SDK is not 7.0 (SDK is' $SDK_VERSION')'
