I encountered the same problem, but my problem can start Xcode, as long as a new project, and immediately collapse.

I finally solved.

A pretend virtual machine, using mac os version snowleopard
2 upgrade to 10.6.8
snowleopard3 Install snowleopard and the latest version of xcode4 iossdk

Then normal, but faster than the lion.
