Does the Penelope Tutorial work in xCode Simlator?

I'm having problems testing out the penelope tutorial.

The program seems to compile find and gets loaded into the simulator. I see the initial Unity3d Splash Screen then it stops and kicks me back out to the apps page.

Does the xCode Simulator not work with Unity3d?

Can Unity-built games run in the iPhone Simulator?

A: No, but Unity iOS can build to iPad Simulator if you're using the latest SDK. However the simulator itself is not very useful for Unity because it does not simulate all inputs from iOS or properly emulate the performance you get on the iPhone/iPad. You should test out gameplay directly inside Unity using the iPhone/iPad as a remote control while it is running the Unity Remote application. Then, when you are ready to test performance and optimize the game, you publish to iOS devices.

I test Penelope on ipod device. It also exit quickly after showing splash screen. There is no error tips showing on console.
