Q:

I tried to record video capture using Xcode Simulator, but the sound does not recorded

I tried to use iShowU HD to make a video capture from Xcode simulator for my app, but the sound did not recorded.  The sound recorded from other applications, like youtube from browser, etc.  But not from the xcode simulator?  
Anyone has some suggestions how to fix the problem?  
Thanks

A:

According to this tutorial, you need to have the correct input device selected in the Macintosh's Sound Preference Pane for iShowU to be able to pick up audio.  
Sounds like you should have "Soundflower (2ch)" (2 channel) selected as your input source.
