title: Creation of Instances of structures in Swift
body: <p>In the Swift iOS Xcode environment, a project begins with template for a View structure. Typically, for instructional purposes, a “hello world” text is inserted into the structure. Then the program is run and “hello” is displayed. The structure itself looks like a declaration, but without an instance being created. The structure declaration itself appears to being run. Is the nested “some View” the creation of an instance of the containing View? Or how does this work?</p>
