I'm brand new to Mac OS X development and to Xcode and the Cocoa framework. I've been working through the "Your First Mac App" tutorial on the Apple's developer website and have run into a snag. I've made it most of the way through but am hung up in the section where it shows you how to use Autosizing on the gui objects. When I click on the slider(or any of the objects) and then select the size inspector I do not have any of the autosize items in the inspector window like it shows in the tutorial. How do I get those options to show up?
