Xcode 4.4.1 crashes in OS 10.9 when I switch to xib. file in my project.
Log shows that problem is connected to iOS 5.1 simulator.
Is it possible to add support of iOS 5.1 simulator in OS X 10.9?
If it is possible how can I solve this problem?

1. install later Xcode and copy SDK from older Xcode? (will it work?)
2. do something only with Xcode 4.4.1? (any way I need to install Xcode 5, but I need Xcode 4.4.1 too)
