Issues after installing upgraded XCode version

Question

I installed XCode DP 4.5 recently - just to try out iOS 6. I opened a project using it.

When I reopened using XCode 4.2.1 again, I started having storyboard data loss issue mentioned here .

I don't get this issue in 4.5 DP, but then I don't want to continue with XCode 45 DP. I am not sure if its valid to build my app with it. Also, it shows me "iPhoneOS 5.0 sdk not found warning" which is the base sdk I have set within my project.

What should I do to get rid of this issue? Is it ok to continue using 4.5 DP? If not, how can I safely go back to 4.2.1? Is there any workaround in project to make, to regain my storyboard? I also have storyboard backed up, but as soon as I import it into my project (within 4.2.1) - it complains it cannot open it. So I suspect it's due to a setting shared both by 45 DP and 4.2.1.

Please help...

Answer 1

Download the Golden Master for iOS 6 and use that for your development. As the GM version App may be compiled for distribution with it and Xcode 4.2.1 will become obsolete.

Answer 2

By default storyboards are set to be compatible with the current release of Xcode, and one previous release. You can choose to make them compatible with even older releases by modifying the development version pop up in the storyboard's file inspector.
