When using Xcode, Interface Builder will not open when I click MainMenu.xib
Hi, I'm new to the developer community. I recently installed Xcode, and I have been watching some youtube videos to help me get the feel for how it is set up. Anyways, on all the videos that I've seen they have you click on the MainMenu.xib thing to open up Interface Builder. When I click MainMenu.xib, nothing happens at all. I'm wondering why this isn't doing anything because I have to open up the Interface Builder manually and then it doesn't link together.
Thanks.
