iPhone simulators crash on app launch

Question

I\'m having some issues with the iPhone simulators after upgrading to Lion and XCode 4.1. When I launch the simulator for 4.0, 4.1 or 4.2 (which I restored from Time Machine

Answer 1

The answer to your problem lies in what you have written: (which I restored from Time Machine).

You are using a restored version of the Simulator that do not match your Xcode 4.1 installation.

Using any Simulator not part of the installed SDK is done at your own risk.
