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...
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.
