Thanks for the information. I wasn't aware of this.

I had made by comment based on not seeing any nibs for describing the  
UI. Actually I saw one (MainMenu.nib),
but could not open it with 'Interface Builder'. I suppose I made an  
assumption without doing much research.

Has anyone put any documentation together on VLCKit?
